We had a lovely stay - Lux & Easy Athens Metro
Suites was comfortable and clean, and spacious enough for 2 adults and 2 teens.
It is a bit out of the way - not near the touristy areas, although you can walk to the Acropolis Museum in about 35 minutes or take a taxi, which ranged in price between about €8-€12 each time. It was nice to be out of the extremely busy, touristy areas at night and as a result, it was very quiet and pleasant.
There are a few, small, local restaurants nearby that were very good value for money.
Overall a great stay!
