Great location in Athens--steps from the Metro, easy walk to the Acropolis, and free shuttle bus to Stravros Niarchos Cultural Center. Lots of amenities right nearby, including restaurants, cafes, grocery stores and bakeries. We were really happy with the location and ended up using the shuttle twice to go to the cultural center for the summer festival as well as walking to the Acropolis twice in order to climb to the top and another time to see a concert at the Odeon of Herodes Atticus. Max and his friend who met us at the apartment in Athens were quick to respond and check-in was smooth and easy, and we received quick responses to our later questions.
The apartment had everything we needed to stay comfortably. If you want to cook be aware the kitchen has only a small stove but we had no plans to cook anything except making coffee so it worked fine for us. There is noise from the street at night--probably no more than most other locations in any big city but light sleepers might want to take note.
Overall a great place for us to spend our time exploring Athens and beginning our travels in Greece.
