Hands down the best Airbnb I've stayed at so far. Wally's apt is squeaky clean, very well-maintained, and conveniently located right next to Sants train station and metro. I know a lot of the hosts on Airbnb just leave the key at the concierge/locker, and you barely get to see him/her during the stay. Wally came to meet us to hand over the keys and showed us around the apartment. He also gave us so many helpful tips on restaurants and places to visit in BCN. I'd recommend this place to anyone and will definitely stay here again when I visit BCN in the future.
