Overall, I thought it was a great place and really enjoyed the view which even locals said was one of the best they've seen: you watch the sun set directly behind the Acropolis!
Apartment was very clean and well-equipped, everything worked well including (very important) the aircon. I really enjoyed the location: not touristy but close to lots of attractions and the more tourist areas if you want to visit those. Laundromat, supermarket, pharmacy, bars and restaurants all within 5 minutes walk. Locals very friendly if you are too. Bed was comfortable (at least for one very tall person) and storage space was enough for me.
It was a new listing when I stayed, so had a few teething problems on access, etc but I'm sure those will be sorted out - Katerina was very responsive and eager to assist.
I'd stay again.
