The neighborhood was right at the city center, off a single side street with a park out front (so quiet, but also close to the action of Barcelona.) The metro is very close. Albin greeted us immediately, he had a bottle of Catalunyan cava waiting for us to celebrate our first night in the city. The apartment is a very spacious bedroom with a sitting area, and a hallway of four doors that include a kitchen, two bathroom parts (shower/sink, and toilet), and the front door. Albin and Sylvia live on the opposite side of the hallway, and this didn't cause a problem. We would spot them in the hallway accessing the kitchen or exiting the shower about once a day, maybe twice, about as often as we would see any other neighbor from the building exiting their apartment onto the stairwell. Albin was always very friendly - the best host we had across five cities.
