The place is lovely! It is a huge space with 3 large bedrooms, 2 bathrooms, a living room and kitchen, and 4 balconies. It's located on the second floor, and the parents of the host live on the first floor.
The beds were very hard, but the House was clean and had air conditioning.
We had a group of 6 and had tons of space.
The location is perfect - it is 1 minute away from st.georges beach which is full of beach umbrellas and lounge chairs and restaurants. It is about a 10 minute (or less) walk to the centre of Naxos and the marina. Perfect location! Here you can rent cars and quads etc.
There is a supermarket about 2 minutes away as well.
The old couple downstairs is very friendly and can help with anything you need. They will also let you know if you have left a light on etc :)
The only problem we had was the wireless - it did not work our entire stay- and that there were no beach towels. But we bought a few for 6 euros which were great!
Highly recommended!
