Drew and Tomar's place is amazing. It is in a great area of Eixample with many restaurants and bars around, the metro station is around the corner, and is fairly close to almost anywhere you want to be in Barcelona (eg walking distance to Gaudi's Casa Battlo and Casa Mila). Additionally, it is very tastefully decorated, and with a pedestrian only street below and the University of Barcelona across the street, it truly feels luxurious.
Communication was also very easy.
