My girlfriend and I returned last week from nine nights staying at La Mer & Dewey House - and quite simply could not find fault with it. All the other reviews are spot on....the location, staff, ambience, rooms and service are first rate.
Beautiful small guest house type hotel, but don't let that fool you - on the whole the rooms are a good size and each have their own individual features. We were lucky enough to stay in two different rooms during our stay and I would have been happy to live in both forever! Right on the beach (and one of very few properties in Key West that are) you also have access to the Southernmost Hotel's pools, if you don't fancy the beach and sea.
Top Tip: If you find sitting in the sun on the beach or round the pool too hot, go and try the supremely comfortable (and free!) sunloungers out on the pier (again only yards away). There's always a breeze blowing there and it provides welcome relief, but watch the burn.
Afternoon tea is included and is ideal....light pastry and cheese snacks, along with excellent coffee and tea. This is surpassed only by breakfast.....which is everything you could wish for in this warm climate. La Mer & Dewey is hosted by Innkeeper John (and ably assisted by Randall) - seek John out for a world of advice on things to do....or even just a friendly chat!
In summary - a brilliant holiday. Loved the hotel and perfect for relaxing break....as well as being close enough to the action if you want something more uptempo!
We will be back!

We searched and searched the web for a great hotel in Key West after booking our frequent flyer tickets to Key West. We found the La Mer And Dewey house on Trip Advisor. We called and made reservations directly through the hotel and were given a better rate than what was on line. They booked us in room 416 for our trip. It was on the ground floor with this porch that looked and opened up directly to this beautiful white sand beach with palm trees. It was private, secluded and very romantic. The room was a little small but the view well made up for that. It was very clean and well maintained. The staff is INCREDIBLE! - funny friendly and accommodating. We had a wonderful 8-day stay. John and Randall are both great host for breakfast making great waffles and pointing you to all the good places to see. Their are NO waves on the beach because of the coral reef seven miles off shore so the water is calm, clear and shallow. You can see the fish swimming around your legs. And yes there is seaweed but you get used to it and they have a tractor that clears the beach daily. Actually we ended up favoring the pier for sunbathing so we could catch the breeze in the hot and muggy month of August -- (love it)

Some thing you must do while in Key West are go the Butterfly Conservatory around the corner, eat key lime pie on a stick, take a day trip to the Dry Tortugas (Garden Key) for snorkeling (WOW!!), have dinner at Latitudes at sunset on Sunset Key (WOW What a sunset!!), rent a car and drive 30 miles north to Bahia Honda National Park, and eat at Blue Heaven in Bahama Village with the chickens.

We did not know what to expect out of this trip to Key West and were a little apprehensive from what we had been told by some people. Thankfully we found the right place to stay and decided to venture out and do some non-traditional tourist things which all added up to one of the best vacations we have ever had. Not a bad way to celebrate 21 years together.

We stayed at the Dewey House and it was very nice. The house was very quaint and charming with an "museum-like" quality to it. The innkeeper John was absolutely the highlight of the hotel. He was very friendly, welcoming and full of local knowledge.
On the downside, I would not recommend this hotel for your honeymoon if you are looking for a romatic get away. Nor would I recommend Key West for a beachside wedding. The beach at the Southernmost is small and public. The middle Keys offer more quiet romantic possibilites. This would totally be appropriate for an anniversary or a couple seeking to find a nice place to stay while visiting Key West.
Its location was great, just far enough from the action of Duvall street but just close enough to walk ( if you are very energetic people). But it was in the middle of the Southernmost Compound, which made it feel very coorporate as opposed to personal. So for us, we felt a little lost in the mix. We were looking for something a little more special. Overall the hotel its staff and decor was very nice ! We enjoyed it!

We absolutely loved the Dewey House! We had a room on the first floor, which we were a little worried about. When we got there, we saw that our room was right next to the entrance. But- it was actually not a problem. It was very quiet, clean, attractive, comfortable, and very big. We had a private porch off of our room with a sun-porch as well. We thought it was sweet and romantic.

It was also not a typical B&B. It did not feel like you were sleeping in someone else's house. We thought this was a plus. Also, it was all couples. It had a very intimate feel to it.

The breakfast was somewhat high-end continental. There were tasty muffins, croissants, and the like. There was freshly brewed coffee and mimosas. Everything was help-yourself, but in a nice way. You didn't feel like someone was hovering over you.

Also, the location was fantastic. It is on Duval, but not the party area. It is right near the Southernmost Point memorial. There was a scooter rental place right across the street. My husband had a blast riding all over the city.

All around, we loved it. We are thinking about going back to Key West in the next year and we will probably stay there again. Also, once we got down there we looked at other placed we were considering, and we were very glad that we chose the Dewey House. It was great!

Also, Blue Heaven was amazing for brunch: 729 Thomas St. Don't miss it. And, if you like to kayak, Lazy Dog Kayak was great, too!
