Joan's studio has a great location, it is near to the center so that one can easily explore the city on foot. There are also lots of cafes and bars in the viccinity. Despite the central location, it is very quiet. The studio itself is small but cozy. I stayed there together with my girlfriend and it was enough space for two of us. The only critique: the bed is a little too small for two persons but for a few days it is ok.
Communication was really fast and professional. We enjoyed our stay a lot.
