We loved Rocio's place. It's in a quite Catalan neighborhood in which you can really feel like you are in Barcelona. No tourists around, lots of nice pastries and "supermercat" just within walking distance. The place was clean, no insects or bugs to ruin your holiday. We even found a Nespresso machine to fulfill our coffee desires :)
We loved Rocio's house and it's been a pleasure staying here. If you want to get into a real Catalonian atmosphere, live like a residence not a tourist, you should take it. It was really good.
