Upon arriving at the Barcelona airport, I called Angie (she handled our check in.) She let us know to take the blue line into the city, but we decided on a taxi instead. Upon arriving, Angie showed us the apartment and let us get settled in. She warned us that the a/c had been acting us, and it would be best to leave it off until that evening. We did as instructed, but unfortunately, the unit leaked massively in the living room. Other than that, the apartment was wonderful. The beds were set up nicely and we had all the amenities we needed. We did have to go buy toilet paper and paper towels, which was a disappointment, but luckily neither of those break the bank :)
Many other reviewers have commented on the distance from city center, and I would agree. I wish we had stayed closer - nearly every metro ride turned out to be around 30 minutes. Nonetheless, we picked the unit bc we wanted a/c and it worked well for us.
