The host offered to pick us up at the airport and take us to the apartment, but he charges 30-40 euros each way. You can take a cab for 15-25 euros or use public transportation for even less. The apartment was okay, nothing fancy; it had enough space for 4-6 people to sleep comfortably. If you go during the summer, be wary of the portable air conditioners. They take a long time to cool any room down and you have to empty the water out multiple times a day. We were out of basic supplies such as toilet paper and paper towels within 2 days and we had to go out and purchase our own. On the plus side, the location was decent as it was close to restaurants, shops, and public transportation. Also, the bathroom was nice and the apartment had a washing machine. If I came back to Barcelona, I wouldn't stay here again.
