It takes about a 13 minute walk from the Plata Catalunya where the airport aerobus drops you off, but the walk is easy and filled with the beauty of the gothic quarter.
The hotel is a great location because there are convenience stores, landmarks, delicious restaurants/tapa bars nearby, as well as a metro station. The downside is the hotel was undergoing some construction during our stay so there was open dry wall and tiles at some spots. The noise might also be a factor if you are a light sleeper and go to bed early as it is on a busy street.
