I had booked the apartment for four nights but already on my first day I decided to cut my start in Athens short and spend my long weekend on an island instead.
Positives first: The apartment is quite conveniently located: close to bars and restaurants, walking distance to the Acropolis. Zannat is a great person, easy to talk to, open and very friendly! Communication with him prior to my arrival was easy.
Now the downsides: I didn't feel the apartment is made for AirBnB. I found it very noisy, the bathroom didn't feel clean (but that may be because it was quite damp and old), the bed was uncomfortable. Because I was traveling on my own, I had specifically looked for a private room in a shared apartment to be able to get tipps from my hosts and to chat occasionally but also so that I could withdraw into my private space whenever needed. I wasn't aware however, that you had to cross your host's bedroom each time you go to the bathroom and the kitchen, or even if you want to leave the flat. This made me feel hugely uncomfortable as I felt I was invading someone else's privacy (and constantly waking him up!) and I couldn't properly withdraw into my room when I was not alone in the flat. In terms of the area, some may perceive it as a little dodgy. While I was okay with it, I can understand that others may feel a little uncomfortable walking around this neighbourhood at night.
Overall, if the apartment had had a second room, I would have felt much more comfortable and I may have even stayed in Athens for the weekend.
