We didn't get to meet Lisa, but the communication through Airbnb was pleasant, and she responds very quick.
The apartment is cozy and beautiful, we had everything we needed. As an avid coffee drinker, I appreciated the geyser coffee maker. The location is very good, several supermarkets and bus stops in close proximity, the Sagrada Familia metro station (and the building itself) is nearby as well. The stairs to the apartment were a bit of a challenge (way up high :D), but manageable.
