Núria was very kind from start to finish. We had trouble finding where she was picking us up but still greeted us with a smile and pointed out helpful particulars (like the metro stop) along the way back to the apartment. We found plenty of places in the neighborhood just walking to our destinations, although you might want to search online beforehand so you know where you're going exactly, especially at night. Pleasant walks to Park Güell and Sagrada Familia. We got to the Cathedral via metro no problem, and my friend and I are no experts at public transportation. If we can figure it out, anyone can. The wifi didn't work for us but we didn't really need it for such a short stay and it was no problem, we didn't even mention it (we think it might have been our phones). We stayed for 2 whole days and 3 nights, and we saw everything we wanted to see. Would recommend for a short trip where you don't mind feeling like you're at sleep away camp with your bunkmates. Núria also gave us a ride to and from the airport and that was a good experience as well.
