The hostess was very responsive to needs. Although there were a few things that she had not anticipated for a long term stay (such as providing a vacuum to clean the place or cleaning products) she was very responsive to providing them. She also had a technician come out to fix the problem with Netflix. She was open to communication about needs and was eager to please the guest.
The presence of a washer/dryer in the apartment was a huge plus especially on the days that clothes could not be hung out to dry due to cold weather.
The location was excellent for my purposes. It was a short walk to the metro, and the Athens Concert Hall. The center of Athens (Sytagma) was a walkable distance (about 25 minutes or so ) or two metro stops. There are a number of grocery stores/markets within the area as well as coffee places, and a few places to eat.
The upper floor location helped to muffle some of the sounds from the very busy street on which the apartment was located.
