We've spent 3 nights with my family in Barcelona. This apartment is exactly as the photos showed : beautiful, huge, well located (easy to find, with transports to go to Plaza de Catalunya or elsewhere) and well soundproof (even if the Ronda is a big road!) . There is a lot of shops nearby.
Only one point are less good : If you are by car it's a bit difficult to park.
Alex is a great host and we recommand this appartment to anyone.
