We stayed for 4 nights. Surprisingly for us, we were the first guests in the apartments.
The location is nice: 7 min to Panepistimio and 18 min to Evangelismos metro stations. A supermarket is just over the corner.
The flat is modern and clean. All furniture is new. Full collected kitchen: all cutlery, a dish set, all cooking electronic.
The hosts were friendly and helped with everything. Highly recommend staying for a weekend or more.
