Ana Isabel's place is superbly located in the Gracia area, with a small balcony overlooking the Placa del Sol. The location alone makes the place worthwhile -- the area is vibrant, full of good food, live music, good drinks, and coffee. That the apartment manages to put you right next to all of this yet still give you a relaxing place to come home to, cannot be overstated. The couple of nights we spent relaxing in the apartment even while the bars went full steam below were as wonderful as those we ventured out. Ana Isabel is a wonderful host who was at all times attentive to our requests and had no problem with our leaving our bags there through cleanup so that we could have lunch before heading to the airport.
In short, had a fantastic time in equal parts due to location and Ana Isabel's hosting. Would highly recommend.
