This is a really wonderful apartment! Designed and owned by a talented architect, this apartment was a pleasure to be in. We really appreciated all of the well-thought-out and beautifully executed design decisions. We were in Athens during a summer heat wave, and the AC worked beautifully. The WiFi is also good, and the apartment is very quiet. The apartment is on a dead-end, pedestrianized street, in an extremely central area, near to parks, cafes and other amenities. We had really pleasant experiences with a lot of very kind shop owners on this street, who were always happy to help us as we fumbled through our interactions in broken, beginner Greek. There is a green grocer, a dry cleaner, a great coffee shop and a mini market all on this very small, quiet street.
Check in and check out were really easy, as was communication with our hosts.
I loved everything about this apartment with a single exception. As someone who is negatively affected by strong synthetic/chemical fragrances, I have to say that this is by far the most strongly-scented place that I have ever stayed. We were there for almost a month, and the whole apartment was still eye-wateringly, throat-burningly fragrant by the time that we left. I brought my own linens and we tried, in a heat wave, to open the windows to air the place out, but to no real avail. If you are sensitive to fragrances, I am afraid that you should pass on this otherwise truly wonderful place.
