We had a great stay at Barcelona in Roberto's appartment. Everything is as described. The space is basic and small, but we knew this in advance and we barely spent time at the Airbnb because we were exploring the city. I would say it is a 3 person max, but only if you know each other closely. It is an open duplex layout and the bathroom door is frosted glass, so there is minimal privacy. Again, knowing this in advance, this was no problem for us. Also I should mention that the walls are very thin, so you can hear the neighbours. Roberto is a great host, he was welcoming and gave us al the info we needed and asked for. He was also quickly available. The location is also great, in a quiet street without any nightlife but nearby several metro lines and on walking distance from Plaça D'Espanya (10 min). There is an amazing Italian restaurant called Meraviglioso nearby that I would highly recommend - great prices, friendly services and the best Italian food I ever had (we needed some pasta before the marathon, but the irony of eating Italian good when in Spain is not lost on me). We would stay here again!
