I lived at Cristina's for three months, together with my girlfriend (we worked in Barcelona during this period). It was a perfect experience: we had our space and every kind of comfort. Cristina is very kindly, she is respectful of your privacy but she is very helpful in any situation. The house is located in an optimal position in the neighborhood, it is very nice as you can see in the pictures.
In this long period we felt like home, I cannot remember any negative note. It was a pleasure living the city from Cristina's house!
