Maria Rita's apt was wonderful. I was only there for a couple days and didn't see much if her but she was there to welcome me with everything I needed (keys, wifi password, towels, and a wonderful room). Her home is very cozy. The location is very central and easy to get to. There are parks, museums and a lot if shops all around. I got to walk everywhere. The shower took a minute for me to figure out (so you might want to ask beforehand) and i sleep early, like 22h or 23h, and one of her neighbors stays awake in the kitchen some of those hours making noise. I put earplugs on and I'm used to sleeping in complete silence so that was a little disturbing but eventually they quit down and it wasn't every night. Anyhow, I would recommend staying with her definitely. Her roommate is very nice as well. Barcelona has great art museums.
