The Fancy Philosopher apartment was ideal for our group of five people (two couples and one single). The three bedrooms all had en suite bathrooms, so we had plenty of privacy, and the large dining table and seating area gave us lots of room to gather.
The area was very nice, with many dining options and small groceries nearby. The Dexameni restaurant just across the street became a regular favorite for us. We were glad that we chose not to have a car in Athens, but you should expect to climb many hills and stairs if you are walking and using the metro. Be sure to walk around the neighborhood in the evening; you will catch wonderful glimpses of the Acropolis between the buildings.
Other reviews have mentioned the noise from the jazz club behind the apartment. My husband and I stayed in that back bedroom, and although we could hear some noise from the club, it was very much in the background, even quieter than the street noise at the front of the apartment. We had no trouble sleeping.
Highly recommend!
