Location is walkable to Acropolis museum (but not exactly too near either; about 2-3 blocks).
Apartment is stylishly designed and modern, although it could have been better maintained, particularly the toilet (black mould on walls).
Staff does not reside in apartment, so you may have to wait a while for them to arrive. The only waiting area is in the lobby of the building, but you have to get pass the locked front door first (just follow other people inside).
