Costas is a great host, very easy to communicate with, friendly and quick to respond. The place was off the beaten path, but centrally located. We had a room on the first floor (which is really sort of like the second floor, in that it's above the ground level), yet it was quiet and felt secluded. The shower is a bit on a smaller side, but everything was clean and worked great. A separate note on breakfast: it was great! The homemade jams were absolutely to die for, I wish I could have more of them.
The town of Adamantas is about 20 minute walk, closest beach is about 15. We rented a car and drove around the island. Overall, I would recommend the place if you're looking for a quiet secluded place to stay that is also close to more lively downtown.
