We really liked staying in the house of Silvia. It was very clean, nice, enough space, a beautiful terrace and a nice bathroom and Silvia is very friendly and helpful. We could make coffee and tea inside the room, use a small microwave and have our own breakfast. The room is located in a quiet area, so you will not get disturbed during the night by noise from outside.
A walk to the city centre is done in app. 10-15 min and a metro station is also close by ( a few minutes walk to Provenca o Diagonal which we used often). You also have access to the bus system and can find a bus station directly close to the house.
A small supermarket is located a few metres away from the house and you find nice restaurants and shops directly in the street Aribau.
So I can recommend Silvias room absolutely and want to stay there if I go to Barcelona again.
