I stayed three nights in Jan. The room is near Syntagma Square so really easy to get to from the airport and in an area full of bars and shops, very close to Psiri and about 15 minute walk to the ancient ruins. I was worried that I might be cold, but the room is super cosy and it was toasty. The house is quirky and the hosts are super easy going. If you manage to catch them you might have a great nighttime chat.
