Alberto is very knowledgeable and generous - he gave us great suggestions and even took us on a personal tour to Montjuc. He provided towels and bedding. Bathroom and kitchen are shared with other people who live in the house. The queen bed is in one room, the twin is a separate room. The twin bed is raised very high off the ground, located in the room pictured with the stuffed animals.
Overall we had a good stay. The neighborhood is near a lot of restaurants and you can walk up to the Olympic stadium and Montjuc from there within 30 min. You do need to speak Spanish to fully communicate with Alberto.
