The best stay I can think of. The hosts there were so welcoming and communicating, it felt like a little family. :-)
If we had any problems they would do what the could to resolve it. They also had a lot of knowledge about the Island and would gladly help, so we were to avoid the "tourist-traps". The place was nice and clean and was placed in the middle of Fira, where it's easy to get to the rest. of the island.
If we were to come back to Fira, we would stay at Giorgos again. :-)
