We stayed for 3 days at Javier and Anna's place. Beforehand Javier send us a map with directions, which made it very easy for us to find everything. He did everything he could to make us feel welcome. For example, when we arrived, he made sure there was something to eat, because it was already late. And every morning he made us breakfast. When we asked what we should see in Barcelona, he pointed us to more then ten places all over the city with Google maps, including places to see, to eat, ... We went to Barcelona before, but Javiers' recomendations made the city a whole lot more interesting then before.
Although we didn't see Javier or Anna a lot, they were always friendly when they were there. The place itself was clean and you had a nice terras where you could sit during the day.

We travelled with three, including my girlfriend. So, the only downside (for us) was that there was no double bed, but we knew that beforehand. I would definetly recommend this place to everyone looking for a nice place in Barcelona.
