Rosa was a lovely host. She met us at the Airbnb and walked us into the apartment to show us the amenities and how to use the train maps. She is so friendly and helpful. Her place is very conveniently located. The first day we were there, we walked to the old town, gothic center with lots of shopping and site seeing. The train was also just 2 blocks away, which was so easy to use. We took the train to all the major sites, including Sagrada Familia, Park Guell, and more shopping north of old town.
