First of all, the host was amazingly friendly: arranged the meting, gave us all advices about neighborhood, helped with our stuff, etc. We were offered with transfer from airport for the price of regular taxi. Was super useful on the way back. So, take into account that it’s totally fair deal and use it. Will save you a lot of time.
Regarding the apartments itself, location is super cool as well as beautiful view of Acropolis. It’s a bit noisy because of the active road which is right in front of the window, so be ready for it. You’ll hear cars going back and forth all the time including night. Can be a problem for some people especially with kids.
Other than that it’s clean, nice, cozy. A lot of space. About 15 minutes of walk from all the main things in Athens.
