The apartment was very spacious, nice and clean. The fragrance of blossoming orange trees on the balcony was just amazing (our visit was in mid April). The location was great, in the city center - we took a walk to the Hill of the Muses one morning.
Our hosts were really hospitable - they took the trouble to wait for us at the Metro station at the Easter evening, when we arrived. Very kind of them. And they really saved me and my family (wife and two kids) by providing some essential foodstuffs in their kitchen, so we didn't have to go out after a long travel to look for something to eat on the Easter evening (when practically everything was closed). I can sincerely recommend this place for anyone visiting Athens.
