Classing this hotel as 4 star is a joke - it's barely worth a 2. When we arrived we couldn't believe the surroundings as it was just scrubland and this was the horrible view we had from our room along with a dirt path. It is not on the beach front. It is very poorly located as it is a very long walk from where you catch the ferries and even further from the old market town near the castle where we found the best restaurants were. The manager was rude and aggressive and on asking about the swimming pool were told we could not use the pool before 10.00 am and not after 8.00 pm. Perhaps this was because it was unheatd and on trying found the water to be icy cold. The beds were so hard we may as well have slept on the floor. Breakfasts were most disappointing; very pool selection of food and the fried eggs looked revolting. Air conditioning was barely satisfactory. Extremely small bathroom and only hand held shower. Bathroom door wouldn't close. I had washed a chiffon top of mine and in the morning found it to be crawling with ants who had eaten holes in it! Definitely give this hotel a miss - there are far nicer places to go.

We stayed at Astir of Naxos for 2 nights as part of our Greek island hopping trip.
We didn't get picked up at the port as the hotel apparently does not do pick ups in the morning as it is too busy - however, if you arrive in afternoon or evening you should try and liaise with Mr Margaritis to get a lift to the hotel and save yourself 5 euros (standard fare to and from the hotel to the town centre).
We arrived at the hotel and were greeted by a friendly elderly man who was obviously the owner. He has a good sense of humour and tries to help wherever possible - he has obviously been a hotelier for a number of years and Astir seems to be his family investment. It's a pretty swish looking and fairly large (for Naxos) hotel close to St George's beach. I'd say it's about 1-2 minutes to the beach which I have to say is amazing. The beach is the best beach ever for kids... it's shallow for such a long way out and is nice and sandy. The section of beach near the hotel is quieter than the town end but I would suggest that in July and August, even this part could get quite crowded.

Back to the hotel... the pool and surrounding lounging area is first rate... it really is. comfy loungers and a really pretty 'infinity' type pool. The room we had was a "honeymoon" room even though we were not on our honeymoon but why not go for a bit extra at the same price eh?? :)
It was a nice room on the first floor with a balcony, clean en-suite bathroom, nice comfy bed and satellite TV. Air con was good and towels were changed everyday. Very nice room.
Breakfast is served in the bar area and was a fairly decent breakfast selection. Not amazing but hey buffet breakfasts never are really! You were able to eat your breakfast by the pool in the morning whcih I thought was nice.

So all in all I think that Astir is a nice friendly, family run hotel which should definitely be considered if you are looking for a beach/pool family holiday on a nice quiet Greek Island.

Great location, not too far out of the town but far enough to not have the noise. The beach is a short walk and some great restaurants around the town. The staff were friendly and hospitable. Pool was nice and all so clean.

We travel to Naxos with ship from Piraeus, we had already made our reservation via internet, and Gianis (the manager of astir hotel), was at seaport before us!
From the first moment until the last everything was perfect. Excellent service, very kind people, clean rooms, nice breakfast and the most important is that they help us to discover every root of the island, whenever we need them they was there to help us, to rent a car for example or some banking affairs we had. Prices was logical for the services we had, but at the bar and the pool of the hotel was really low... i will say cheap.

So, that was a very nice vacation for us with a real top quality accommodation and we think about to repeat that next summer.
