We loved staying in Marios and Sotiris' place! Travelled as a family of 3 (with a 3 year old). Really nice apartment, big rooms, spacious bedrooms with loads of storage space, comfortable showers with good water pressure, AC in bedrooms and living room. A really excellent location - 1min wall from metro station, right next to some great eating places and 10min walk to the Acropolis and main tourist sites. So convenient but also quiet at night. Excellent bakery and small supermarket right next door. Sotiris also helped organise a taxi from the airport for us which was really helpful! Perhaps would be a plus to have a few child-friendly things like some books or games, but that would be a real bonus and we weren't expecting anything like that!
We would loved our stay and would definitively recommend!
