Spacious, clean apartment in a safe, calm neighborhood. We stayed 9 nights and enjoyed being away from the major tourist areas but not far from subways. We had 5 guests and were able to spread out nicely in the apartment...three teens enjoyed having their own rooms. Master suite is upstairs, so not good for those with mobility issues (but neither is Barcelona as a whole!).
Maria was out of town during our stay but happily answered my questions via WhatsApp. Her mother met us and let us in... (she speaks little English, but communicated well enough), and Maria has a binder with helpful information. Highly recommend!
