Mario's place is very beautiful. He was there to greet us upon arrival and answer all of our questions. The apartment has a very modern design and was very roomy for the 3 of us. The location was decent and was around a €6-7 cab ride to wherever we wanted to go. The cab was cheaper for the 4 of us then taking the metro. Plenty of places around the apartment to eat or drink. There is a jail directly across the street but the neighborhood felt safe and quiet during our visit. The AC was not working in the master bedroom during the visit but the rest of the apartment was very comfortable during the stay. The would stay again for future visits to Barcelona.
