Margarita & her son were wonderful hosts for a month. They welcomed me in their home, helped me practice my Spanish (though they both spoke excellent English), and I was lucky to get to hear her son (a professional pianist) practice a few times.
The house was situated perfectly for me to do some heads down work away from the distractions of the city, while still having it accessible to enjoy when I had the time. The house is comfortable and peaceful, it's situated in quiet neighborhood surrounded by forest, and the walk to the funicular has stunning views of Barcelona. Their kitchen is large and luminous, and well equipped. I highly recommend staying with them.
