We stayed 5 nights with a family of 5 in this apartment. It is well situated for a city trip in Athens. You can walk quite easy to the centre and there are enough coffee bars and grocery stores around the corner for good breakfast and coffee.
The facilities in the apartment and apartment building are very good. you can even workout and do your laundry.
Mary and Esmeralda are very helpful, for example when you need a transfer or when there is a problem. She arranged a technician in a few moments for us when the warm water wasn't working. Very professionally organised.
