Jacopo's place is the best Airbnb I can imagine in Barcelona. The room is small, but comfy. The location is supercentral, so you can get to the Placa Catalunya by feet in 5minutes and it's also metro just around the corner. Jacopo is great host and great person. I felt really great during my whole staying in this room. I would recommend it to any solo-traveler who wants to live in nice flat with great guys! ;)
