We had a wonderful stay at Maria's apartment.
The apartment is very well furnished and spacious (a special mention for the really comfortable sofa!) The location is perfect - very close to the port and centre of Naxos Town, whilst also slightly tucked away so quiet at night.
Maria is easy to communicate with and was extremely kind throughout our stay. Our ferry wasn't until late afternoon and there was no-one staying the next day, so Maria allowed us a late checkout and her brother also transported our cases to the port.
A great stay and one we would highly recommend.
