We had a nice week in Barcelona here. The apartment is spacious and well kept, clean on arrival, with a complete kitchen, washing machine, 2 bedrooms + room with sofa bed, WC, bathroom (with additional WC) and living room with TV. One bedroom and the living room have more light from large windows which open out to a small balcony. We slept in that bedroom and the bed is comfortable.
The location is adequate: if fit, one can walk to/from the main areas (Passeig de Gracía or Placa Catalunya are 15-20 minutes), if not, metro stations are all about 10 minutes away or bus 5 minutes (on Gran Via).
Unfortunately in our week Eberhard & Aurelie were not in town so we did not meet them. A colleague handled check in/out professionally but we missed a bit the expected "personal stay" feeling of using AirBnB.
