It was great staying at Yolanda's apartment. It is in a great location next to a major Metro station which also had a nice shopping mall which was one a bull ring. Being so close to the Metro as well as the bus lines and the Aerobus, which is the bus line to and from the airport, was very convenient.
Nearby is a great city park with a museum and other attractions. Everything else is accessible through the Metro including the train system for day trips such as Montserrat.
The apartment for our family with our two children each having their own room. We were able to save money eating breakfast and some dinners at home and there is a nice supermarket right around the corner.
We really enjoyed our stay and were sad when we had to leave to go back home. Yolanda is an excellent host and promptly answered all of my messages and was very helpful when I had any questions regarding Barcelona. I highly recommend her place especially for families or small groups.
