Excellent location! Easy to access by train from the airport, and RIGHT across from Sagrada Familia. Many restaurants in the neighborhood. Great central location for exploring the city by train or by foot.
The apartment itself was ok for a short stay, but is in need of some serious maintenance. Walls are scuffed, paint is peeling, and construction on the building blocks the view of Sagrada Familia that you see in the pictures. The second bathroom has a terrible sewer smell-- we closed the door and did not use it. The door to the toilet in the other bathroom doesn't latch closed, so there's no privacy and it takes up a lot of space in front of the sink.
Alba was a responsive host, and we had no trouble checking in or out. The price/location mostly balances out here, but don't expect it to look as shiny as it does in the listing photos.
