The room: as described, clean sheets, clean room, clean towels. Hot water available 24/7, kitchen with fridge if needed. We feel safe in the 4 rooms apartment.
The host: the nicest host I ever had, Xristos was extremely helpful and will give you good advice during your stay in Athens.
The extra: I took the airport pickup lift he offer for 23eur. Nice ride and felt safe for a first time in Greece.
I recommend Xristos rooms, it is affordable and clean.
