I spent 3 days in Pia's appartement with my mother, my sister and my husband. The appartment was very clean, functional and well located.
But there were two bad surprises : unfortunatly, we were so cold in the appartment. It was like the heating system didn't work, i don't know why. And we had a problem with the shower too. The water was cold-hot, cold-hot... Impossible to regulate the temperature. I am sure the appartement is really cool during summer but during winter, it's a bit too cold. By the way, the stay in Barcelona was very nice !
