Mar's flat is absolutely beautiful and charming. The layout is great, and very good for a big family. We were in 7 and slept comfortably in the flat. The location of the apartment is very central and easy to get to great restaurants, La Boqueria, La Sagrada Familia and other Gaudi sites. We were able to walk to a lot of different locations. The WiFi was very stable and a good speed which is great for me, since I worked while I was visiting Barcelona with my family. I would highly recommend Mar's flat!
