We had a good stay at Ruben's place! The communication before and during our stay was super easy. The first night was really warm without AC or a fan, but Ruben was super nice and found a fan for us for the other nights.
The flat is closed to several metro lines.
We wanted to stay in a airbnb for a bit more privacy, which unfortunately was not really the case as the other room was also rent, so we had to respect some common life rules such as wearing a mask inside the flat and sharing the bathroom.
