We booked Nik's appartement on very short notice but Nik didn't mind and was very flexible to check us in. The appartement is very nice and located perfectly in between all central places of interest like Monastiraki, Plaka, Acropolis and even Psirri where we ended up that night. Even in front of the building is a nice little square with some bars full of locals which gives it a great atmosphere. It has nice bedrooms and all was very clean. Nice place for a good price to discover Athens!
