The house is huge and very beautiful. You can feel that somebody's living there normally. 5 minutes walk to the Metro and then 10 minutes drive to the old town.
The House has a nice terrace and nice balconies, sunny until afternoon.
We didn't met Paula, but a friend and the father, both very kind and gently. The gave us usefull hints end help.
Everything was fine!
We recommend this house and would come back again for a stay in Barcelona.
