The house wasn't too clean. The living spaces are a bit small for 5 guests. The building is not well soundproofed so its easy to disturb the neighbours (watch out) and vice versa (maybe bring some earplugs)! The house is well equipped with all domestic appliances and services you could hope for, although some have a really cheap vibe (hairdryer didn't work properly, wifi not the best, shower holder broke, toilet stop working for a while and then magically started flushing again). That said, the house is in a really good location, quite at night but close by foot to the Sagrada Familia (10min), a metro station (5min), the very pretty Hospital pf Sant Pau (5min), a bus stop that takes you directly to the beach (3min) and nice places to eat some stuff!
The house is not cheap, but probably cheaper than most. If you are planning to visit for a week or less, it's a fine choice!
