Sarantos is a great host who always responded quickly to my messages and was always available when needed. We had one small problem of the air conditioning leaking overnight but as soon as we told Sarantos he came up to try to fix it, and then managed to get someone in to fix on the same day. Apart from that we had no issues. Although the apartment is quite small, it's fine for two people, and the roof terrace is really spacious, private, and has a view of the Acropolis! There are also lots of chairs and tables so you can easily and comfortably spend most of your time out there. The location is also good as it's only 2 metro stops away from the Acropolis (or a half hour walk) and there are lots of cafes nearby the apartment too. Overall we had a very nice stay and would recommend Sarantos' apartment to any couple/friends exploring Athens for a few days.
