Rented Unit 105A from owner David Delgado. Was to be there for 5 weeks, 2 adults, 2 kids, 1 small dog. Staff was very rude from the get go and a lot of the owners don't like renters/ guests so they try and make your life miserable. Rules are only enforced when they want to bust your @$$. One owner in particular spends her time trying to run out non owners.

After about 3 weeks she convinced management that we should be booted because of the dog (cleared in advance), NOW only owners can have pets under 30lbs..

Owner of Unit 105A, David Delgad was of no help but said he would refund remaining balance. Complete lie, he just hangs up when I contact him.

This place used to be good but is now run down, staff is lazy and rude, and many owners do not want non-owners on the proiperty. Many other choices in Mazatlan. STAY AWAY!

I read the reviews prior to coming, but didn't believe they could be true....boy was I wrong ..read this before you book.
The hotel staff must really hate their jobs, they were the rudest "hospitality" staff I have ever encountered. We had four people, but were only given 2 towels ( no wash cloth's, hand towels, just two ratty towels ) because " it isn't the season for towels.
The room was very cramped, and the furniture was made out of some kind of weird plastic and very uncomfortable, don't ask about the beds, they were worse.
I can't comment enough on how rude the front desk staff and the small store staff were.
If you are from North America, this place seems to have a big chip on their shoulder. I would never stay here again, and I would encourage you to find other lodging in Mazatlan if you are planning a stay.
I was traveling with my three children, ages 21,16 and 14...we would have been much more comfortable in other lodging.

This is a great beach, very secluded and quite. Uncrowded and fun. I give it a 5 star for the beach.
Pool was ok, grounds were nice. 4 star.
A cab ride into town runs around $6 one way. This is a great place if you want to soak up sun and play in the surf. The beach made up for the older and sort of dirty rooms. The maid came everyday and we got clean but ragged towels, clean bedding and houskeeping for 70 cents a day. The rooms had one front bedroom w/ an ocean view and balcony the other bedroom was in the back and faced the outside hallway. Not a good condo for two couples, good for a family where you can put kids in the back non oceanfront bedroom. Rooms get a 3 star. The service is a 3 star, take some patience, it's not the US, thank God. It helps you slow down. You may want to bring your own towels and do wash, they have laundry rooms. The beach towels were very nice they provided.
The price for two couples in a 2 brm was a very good value. I would have paid more though for a better room.
We went with 10 adults(5 couples ) so the back to back bedroom was a problem. I would go back again and get the one bedroom/oceanfront rental from a private party not an Interval getaway.
Or even better,rent the penthouses.

The condo has a good outdoor restaurant for breakfast and drinks at night.
Down the beach to the right you can walk to one of two places for lunch/ dinner. Great food at the one on the beach that is about a 15-20 min stroll.( by the big rock).Very good food in this town.

The outdoor pool bar is ok. very slow.

We hired a van to take us to town everynight. It cost 5 couples very little. He took us on tours, to the lighthouse, dinner/ lunch, and to the boat to go to Stone Island. He was always ontime to pick up and to take us back. We used him to take us back to the airport too. If travling in a large group he would be great:
Special Van Services
Jose Garza
call 669-450283 He speaks great English

Antonio at the condo can set up most activites.
Try:
Stone Island. The sea kyaking even if you never have it 's fun and easy.
The Shiek for dinner(adults, men need long pants, business causal) at Valentino's. Very beautiful setting.
Hike up the lighthouse hill for the best view.
Dinner: Lola and Pedros; The Shrimp Factory; The Shrimp Bucket

During our stay at Costa Bonita we called it a "ghost town." There weren't too many folks around. It was a very quiet and peaceful place. The staff was friendly but not overly outgoing. As far as the guest population I would say it was predominantly older people. There were some families, no college kids, and I think my husband and I might have been the only young couple there (we are both 30). This is definatly not a party hotel. While I was definatly not looking for a party hotel there didn't seem to be anything going on. The signs said that the resteraunt was open all day and that the bar was open from 11AM-10PM but everything was shut down by the time the sun went down and we could never figure out when the resteraunt was open. The door was always shut. Our first day there after a long day of traveling we had no pesos and were desperate for food. We finally just barged our way into the empty resteraunt. They were happy to serve us but until we opened the door they appeared closed. There was never any problem finding a spot at the pool, plenty of chairs. It was always very quiet and serene. No loud music, no screaming people, very few children, I think our last day there was the first time we really saw children playing loudly in one of the pools. The beach also was easy to find a spot on. They only have a few palapas so if you want shade you do need to get up early or hang out at the pool but there is a lot of space on the beach just by the nature of the miles of empty beach in Mazatlan. And there was a nice employee at Costa Bonita while we were there getting people beach chairs and the pads that go with them.
The strange thing about this "ghost town" is that at night in our room we could hear everything echoing in the hallway. Even though there did not seem to be many people there we could hear everything in our room. It was definatly not sound proof. The room we had was very near the entrance however.
We had booked a junior suite. We had two full size beds which were tiny. My husband is very tall and he definatly didn't fit. The beds were also incredibly hard and uncomfortable. Also they charge you for everything. They change the towels every four days and if you need towels in between they charge you $6 (American). You have to do your own dishes or they charge you $6 (American) which is fine but we had no dishwasher and we had no soap and no sponge for us to wash them ourselves.
It is very possible that these things are provided in the regular suites as they do have dishwashers in the bigger suites.
I would say that Costa Bonita is the perfect place for someone who is looking for a very quiet vacation and likes to go into the town (which is very easy) for the things that this hotel doesn't provide that most hotels do. Our stay there was not at all marred by the little things that we disliked.
