The place is a little run down, it needs some serious repairs to the shower, which I have advised.
The walls are also super thin, and everything in the apartment block can be heard as if it’s right in your space. The neighbour’s ‘nocturnal activity’ likely wouldn’t be a welcome part of anyones stay.
Otherwise, check in was easy and simple and the building seemed secure. Short walk to the metro, and Collblanc has some weird charm, unlike any other part of Barcelona which was pretty funny.
All in all, it it’s listed for cheap, go for it. If you’re unlucky enough to get it expensive like myself due to the festival and being cancelled elsewhere. Avoid.
