My husband and I stayed Roberto's place for five nights. The location is perfect to explore Barcelona, it took five to ten minutes to two metro stations and both of them are well connected to many touristic spots and the bus terminal. The room, the kitchen and the bathroom were clean and well equipped with all the amenities we needed. Also Roberto was flexible. When we came to his house, he was not there so he kindly arranged a person to let us in the room when our schedule changed.
Downside was there was no dining space, it is written on the listing though. So we had to have meal in the room. Plus, there was no house rule banning smoking so we understood someone could smoke inside. However, we do not smoke thus it was uncomfortable for us when the smell of cigarettes came into our room.
