We arrived at Saint Vlassis on the 14th of June and stayed 5 nights there on room 205. The rooms were pretty nice and clean with a view overlooking the nearby area (a farm). Beds were comfy, a bit hard for my taste but you could choose between different kinds of pillows to how you preferred it. Breakfast was pretty good and varied for such a small hotel, with scrambled eggs, bacon, fruit, bread, cheese, ham and so on. We ordered a room with a jacuzzi, but I was a bit dissapointed by the fact that it was a bit small for two people to sit in.
The place is a bit out of town, which means you must walk around 5 mins to get to the beach and 10 mins to the city center. Being a bit outside does has it benefits though, as you don't get much of the noise that you get closer to the city and that you get to exercise a bit and get to watch a bit more of the city.
What really makes this place stand out from all of the rest, is the above and beyond, superb service delivered by Kostos. He was always ready with a smile and a laughter, with great tips on where to eat and what to see in Naxos. He was always helpful and whatever your problem or your request was, he was always there to help you with it.
There is no pool at this Hotel, which would've been nice but the nearby beach makes up for that.
