We can absolutely recommend this Airbnb. The roams are simple but clean and fresh. We have stayed here 3 nights. Big advance, it's very nearby the metro, a perfect starting place for the day. The neighborhood is okay. A bit dirty and busy. The apartment itself it quiet and has everything you need. This area has a lot of typical Barcelona restaurants.
Only negative points, you get only one time a fresh towel, you can not change the temperature of the air conditioner your self. The first 2 night we have asked for 21 degrees, that was way to cold. They have changed it lather (after many SMS en mails) to 23 degrees. That was good.
There is an elevator, that makes it very easy with all your luggage. Next time we will book this again.
