This apartment is conveniently located and that is what you're paying for. It's next to the Sagrada Familia, but far enough away to be quiet and not have hoards of tourists at your doorstep. The bed were very comfortable as well.
However, there are a few things that potential renters should know. The second bedroom with the twin is very dark and its only window opens to the stairway. The picture makes it look brighter than it really is. That bedroom also is very noisy because it faces the stairwell and has no AC. It wasn't a problem for me because I wasn't there in the hot months, but if I were, I believe it would be very hot. The apartment is also slightly worn from use that doesn't come out in the pictures and suffers from minor maintenance issues that other reviews have also commented about. When my host checked me in, he pulled a kitchen cabinet to show me where the silverware was and the door came off. The toilet paper holder also came off because it wasn't fastened. Not a big deal because a screwdriver would take care of it, but this apartment gets a lot of use.
All and all this is a comfortable place to stay and is one of the few places with a washer and dryer making it nice if you plan to stay longer. The hosts were very responsive and if they are able to fix some of the minor issues, this place would 5 stars instead of 4.5.
