I had a lovely stay at the flat. It is very close to the metro station, the Gaudi parc.
The flat is well-equiped with a lot, a lot of painting of the owners, which you may find yourself deep in art (or else, depend). My stay was just in 3 days so I didnt manage to utilise all the facility there. But you have to use the terrace, which is so lovely for any outdoor activities.
Paz offers us a bottle of wine from Barcelona as well. That fits perfectly with the terrace :)
