I stayed 10 days in the room and I had a good time there! Zak (Yassines brother) was taking very good care of me and was helping me very much!
The room is as you can see in the pictures and Zak lives in the same appartment and it has another room which you can rent via airbnb.
Just notice that you cannot lock the room. For me it was no problem but maybe somebody else doesnt like that. In the time I was there it was also very hot in Seville and in the room theres no AC so it can get quite warm in there.
Thank you very much again!
