My boyfriend and I stayed here for 5 nights and really enjoyed it. It is an old apartment, but very clean and spacious and really felt like home. We loved having a balcony and the bed is very comfortable. The street itself seems a bit dodgy but there are main streets a couple blocks away. Krystyna was an excellent host and we appreciated the driver Chris picking us up/dropping us to the airport.
Would definitely recommend especially if you want an authentic Athens experience! :)
