I was staying during a heatwave. AC works as it should, a terrace was unusable because of temperature during the day, but near 8 PM it was great because you could really feel a chilling breeze in the evening and this large terrace is the best thing in that apartment (you can see Acropolis from it). The number of power sockets and their locations is a plus. I would complain about the lack of a shelve in a bathroom and the fact that photos from the offer were taken years ago and furniture faded since then. The checking-in process was very convenient, the host replied quickly, overall my experience was pleasant.
