We really loved the location of this flat - it was near both the Metro and the tram, and we could walk to the beach or to many places in Poblenou or Sant Marti. There are also two supermarkets right across the street and many restaurants nearby.
The flat was a bit cozy for our family of four, but it had most of the things we needed, including a washing machine and a drying rack. The sofa bed more comfortable than the average sofa bed. We did have a problem with checking in via the Smartlock (not enough info on how it worked) and some issues with the window shutters (several were broken) and the A/C (the fuse in the fuse box was switched off, and it took us a while to realize that was why it wasn't working). However, the communication with the host was good, so I'm guessing that those issues will get fixed.
