The apartment is in a handy location in a friendly neighbourhood. This is not a hotel zone, so you can see how the locals live. There are lots of amenities nearby. One of the best coffees in Athens is about 12 mins walk (EXO).
The apartment size is fine for 2 people, the wifi was fast and the bed was comfortable. The balcony was a great place for people-watching. The kitchen is tiny and a bit tricky to use, as there wasn't a microwave or oven to reheat our leftover moussaka :-(.
We didn't meet the host, but the communication and check in was excellent.
Overall I would recommend staying here for a short stay in Athens.
