The apartment has a really good location. The neighborhood looks calm, quiet and safe.
Worth to mention that cleaning price is not included, so you are either charged extra 45 EUR or asked to clean it yourself and present it in person at checkout. The apartment was relatively clean though, all was good apart from a bit dusty kitchen worktop and bath towels smell like if they were not fully dried some time ago.
We were told washing machine had broken just before our arrival, but there's some laundries around, so not a problem.
Beware there's security cameras in living room and hallway. Despite that in the flat amenities it's explicitly mentioned there is no cameras.
Might not be a concern for some, but would be fair for the host to mention it.
Another important thing is that the flat lacks fresh air. Bedrooms and bathroom have windows opening to the building's tiny hallway, and look towards the neighbors's windows which are just 1.5 meter close. The windows in the living room looks into a wall of another building, and it's also just 1.5 meter away from you. There are fans in every room, that makes life little better, but expect hot nights if visiting Barcelona in summer months.
