The place looked clean and cosy, same as it looks on photos. I stayed there for 1 week with 6 adults and 2 kids. Place is okay for 9 people but fewer people will feel more comfortable for sure.
Everything was great, especially location, it's 3 blocks away from Passeig De Gracia (The main street of the city) which was fantastic. Check in and check out instructions were super easy and useful, thanks to the host for that.
The only thing I missed in the apartment was Vacuum Cleaner, it was difficult to clean the flat without it. Also, bunk bed made some noises while sleeping on them. It may be more suitable for kids rather than adults.

Other than that, everything was super good. This flat made our trip to Barcelona even more unforgettable.💓
