The apartment is lovely!
It is fully equipped (kitchen/bathroom/bedroom) with everything someone might need during their stay. The location is beautiful for walking around, close to the Metro Station and all the shops/cafés/restaurants in the Acropolis/Plaka area.
The apartment is on the ground floor which may be an issue when sitting in the living room as you do not have privacy without the blinders. Also, the bed is very squeeky, which isn't a problem per se, and the TV was not functioning due to a damaged cable.
The agency was very helpful and sent confirmation/reminder emails on a timely manner.
Overall, a very pleasant experience!
