Overall we enjoyed our stay at this apartment.
First the good: the location is fantastic. It is close to everything we wanted to see and do— the acropolis and other ancient sites, dining, shopping, etc. No taxi or metro needed. The apartment is clean, has air conditioning and a working elevator so you don’t have to carry your bags up flights of stairs. We arrived late due to our airline changing our flight schedule and the host was very accommodating and arranged a ride for us.
Now the bad: we chose the place in part because of the rooftop terrace with views of the acropolis and city. This was closed. That caveat is in the description of the property but not clear enough. We really wanted to enjoy a drink up there in the evening but had to find a rooftop bar nearby, which set us back 50 euro. Second, the beds are a bit uncomfortable and led to some sore backs. Finally the shower has no place to mount the hose so you have to hold it in your hand which is tricky to do if you have mobility issues.
Our conclusion is that it’s a great place to stay for a couple of nights if in Athens for a short time like we were, but may be uncomfortable for a longer period.
