The place is nice and clean, it is located in the heart of Athen's city center, close to all the action but ib a quiet alley. During our stay we wanted the owner's attention to a few minor things, like a bulb in the bath etc. sadly he didn't reply us.
The entrance to the building can be more welcoming, but it isn't something that affects the stay.
Over all we were really happy and enjoyed our stay. Worth the money.
