Steve was very helpful in providing information beforehand, and both Isabelle and Steve were very helpful and responsive throughout our stay. When I pointed out that a fan was broken it was replaced with a new one on the same day. We also were late in giving our arrival arrangements but Isabelle was extremely flexible and accommodating in making sure she was there to meet us.
The flat has tasteful and simple decoration, making good use of the space so it feels uncrowded, the wifi is fast.
The location is wonderful, on a pedestrian street right in the heart of Barcelona with plenty of life all around (bars, restaurants, museums). This can make it a little noisy at night so this place may not be ideal for light sleepers, but that is just what comes with living in the vibrant heart of the old city.
