Unfortunately I couln't stay in the house of Yile because of an urgency the host got the same evening I arrived. I had to find another room in urgence.
I'm still rating the host 5 stars because he took the full responsibility of the problem and was able to solve it. Our communication remained respectful. So knowing that problems can happen to everyone, I still believe Yile is a serious host and would recommend to stay at his place.
A last point is, I didn't see his place but I can say the location is absolutely great. Easy to arrive from the airport (by bus in my case), his building has a lift and it is ideally situated for visiting Barcelona.
