My family (me, my wife and two adult children) just spent five nights at Anne's flat in Barcelona. We really enjoyed our time here. The location was perfect, walking distance to many restaurants, shops and the popular destinations, nearby to the subway stops, but still off the busiest areas. The flat wasn't luxurious, it was more like a 3 or 4 star hotel, but it was clean, was large, and it fit our family well. The room air conditioners had a little trouble keeping up the first couple nights when it was so hot out, but they did well enough. The house free wifi was strong and consistent throughout the entire flat.
Communication was great with Anne, and David was exactly on-time to check us in (even though we arrived so late in the evening - 23:00). We'd definitely recommend staying at this flat.
