The apartment was clean and comfortable. It is close to a few metro stations (within ~1-2km), all of them at walking distance. It is also very close to the City Centre - Monastiraki Square & Plaka, so overall the connectivity is good.
However, the apartment is a little smaller than the pictures suggest and the lighting is a little dim. Also, there is no cleaning service in case you plan to stay for a longer time. Otherwise, the amenities are value for money and the host is pretty reachable almost at all times.
Just a tip, do remember to carry universal electricity converters if you intend to travel anywhere in Greece. In case you forget, there is a shop/ convenience store down the corner of the road, however it is pretty expensive 7-10€ compared to other places.
