The location is great, it's just by Sagrada and subway station. Very convenient. But that's about it for the advantages.
Unfortunately it's too noisy. Not just from the street which, thank god, settles around 1am, which is not too bad. But one of the bedrooms has a window inside the building into the stairs. This side doesn't settle ever. Late people go up and down till around 4-4:30am and then early risers start leaving around 7am. The stairs have a terrible echo so each time somebody walks there you can hear it in that room. If people decide to talk while walking it gets so noisy that it's impossible to sleep there.
So, the listing advertises two bedrooms but in fact there is only one that can be used. For three people one will end up sleeping on the floor.
The state of the apartment could be better. It definitely needs some renovation.
Kitchen is missing a cutting board, shower is missing even a smallest shelf where you can put shampoo and soap while showering.
Cleanliness could be better, kitchen floor had a sand or some debris on the floor, we could feel it though the socks all the time.
