The apartment is in a great location, a short walk from the Sagrada Familia and metro stations. There are also plenty of shops and restaurants nearby. We were also able to check in very late (after midnight) as the host left the key for us in the mailbox of another building just around the corner. The apartment is very nicely decorated and with a modern kitchen with everything you could need.
The windows of the apartment have no views except for the backs of other buildings in the block, but they do get a bit of sunlight in the morning. The window of the second bedroom faces a narrow internal space in the building and has virtually no natural light.
You can also hear quite a bit of noise from the neighboring apartments.
Overall though we had an excellent stay and would gladly stay here again.
