I would absolutely recommend Al & Milla's place! You have a separate bedroom with a balcony and some storage that you can lock and a shared bathroom and kitchen. Everything was really clean and the rooms are nicely decorated. The apartment is situated in the lively neighborhood of El Raval and the surrounding streets are really busy but the room looks out to a quiet patio. The bed is comfy and the shower has fine water pressure. :) There's a small elevator that takes you up to the second floor. Nearby are buses and the tube station Paral-lel. La Rambla for example can be reached on foot. In the close neighbourhood (Rambla del Raval and by the Filmoteca) there are a few restaurants and nice bars. Communication with Al was perfect, he usually answered within minutes, and also they were very flexible with our late departure. Two thumbs up!
