Juanmi's place is wonderful, comfortable, and filled with light. The best part is the incredible views of the city right at your feet. We also were very happy with the location as it's just steps away from a metro station, shops, and restuarants. Juanmi is also very kind and nice to talk to. He gave me lots of suggestions for wines to try, nearby restaurants, and how to get to several of the major tourists sights. He even helped me arrange for an early morning taxi back to the airport.
The bathroom is nice and big and has both a tub and a shower. The kitchen is also really good, although we didn't have a chance to cook. But there is a washer/dryer in the kitchen that was incredibly helpful for us as we were nearing the end of our trip.
I would stay here again next time I come back to Barcelona!
