Our flight arrived after 10pm, but Juanmi was there to greet us with breakfast for the next morning and with restaurant, bar, and club recommendations. He also spent about 10 to 15 minutes walking around the apartment, making sure we knew where everything was and how to operate everything.
The apartment was very clean and in a great neighborhood, central to just about everything. We only needed a taxi or the metro a few times during our 3.5 day visit.
We urge anyone looking for a place in Barcelona to stay here!
