We were very happy to have chosen this place to stay in during our time in Athens. Most people have mentioned all you need to know in their reviews:
The cons that the place doesn’t get a lot of natural light and that you can’t run the hot water while using other electric things like the hair dryer.
The pros that it’s a large space that’s decorated adorably, is in a good location (depending on your priorities, we enjoyed walking there from the more central areas near the acropolis), has lots of snacks and supplies for you to use, and Michael and his father are great hosts (communicative and kind).
We’d definitely stay here again!
