We were a group of 5 friends who wanted a unique experience. We found these apartments online at an internet cafe while we in Santorini. With only a day's notice, we had booked 2 apartments. The apartment manager met us at the ferry port and took us to the apartments. Just look at a map of Naxos and you will see how the alleyways are are around the castle!! I was lost every time I tried to return to the apartment!! What fun!! The apartments were darling, fully furnished with an adorable courtyard. It was just like living in a castle (OK not luxuroiusly, but totally fun and clean).

We stayed in a 3 person studio for 45Euros per night off season.
The room was so convenient for the ferry / bus station, museums and best tavernas.
Except for 1 night it was very quiet - I think a family moved in and were a bit excited at a weekend away so their first night was noisy.
Vangellis was very helpful and even supplied us with free sachets of sugar as we forgot to buy some.
The building was very old, and included an archaeological display under the perspex flooring!
The shower was hot.
The only thing was that the bed was one of the harder Greek mattresses.
It was great to be able to make tea/coffee. We didn't try to cook on the hob, bu there was a mini market and bakery within 2 minutes walk too.
Really enjoyed our stay.
