The modernist decor in the apartment, as well as the staircase is really authentic. Kitchen is well equipped and the place has the right size. Location is great, close to all the bars and restaurants and shops, but in a quiet street and top floor, so really quiet at night. Fatma was away but she was very quick to reply, and Hassan met me at the door and showed me the apartment. Both speak very little English but they were willing to assist and very helpful. Really good hosts.
The downside for me was that the place needed a deep clean. You could see bathroom and kitchen had been cleaned, but the place was dusty and some kitchenware was still dirty (the expresso machine had not been cleaned so there was still coffee in which had grew mold). Moreover, because everything is quite old (sheets, towels, the bathroom, etc.), it made it look unwelcoming. Also, the bed is REALLY uncomfortable (also a quite old bed). I read it on the reviews, but I sleep anywhere so it didn't concern me.
With a deep clean after each guest, new sponges/wipes in the kitchen, a new bed (this one you could feel the springs), and maybe new towels and sheets, I think the place is top election. Also, it is a 5th floor without elevator, so if you are not used to stairs, that might be a problem (it wasn't for me).
