The place is located one block from La Sagrada Familia, with two metro stations within walking distance, so the location is really nice, although there's a kindergarten, so it might be quite noisy at times.
The place itself is quite good, pictures capturing the atmosphere rather accurately. However, the bathroom feels a bit old and one of the rooms is very small, so I would recommend it for two persons. It is also very dark, without any windows. Actually, the whole place seemed a bit dark even during the day.
If you won't be planning to stay there during the day and you're looking for something that can accommodate more people, the value for money is good.
