Great location close to metro only 3 stops from Acropolis. Lots of local shops and restaurants nearby that are not full of tourists. For something more upscale, Gazi district is a 5 minute walk away.
One note: athough the street is not busy, the walls are thin and outside noise such as passing vehicles and garbage trucks in the morning are very loud. Bring earplugs. The bed is not the comfiest.
Hosts were awesome, communication was responsive and friendly. We had a small problem with a broken balcony door that was fixed right away. Kitchen and laundry amenities were good. The flat is basic but clean and tidy with everything you need.
