We stayed for 4 nights as part of a trip to watch FC Barcelona. The Nou Camp was 10 mins walk away.
The apartment was a 2 min walk away from the placa del centre metro line and was easy to find. It helped that Oscar was looking out for us as we walked along the road. The apartment was clean and had everything we needed for our stay. The bedrooms are at the rear of the property so there is no road noise. One bedroom has an ensuite with bath and there is a shower and toilet off the main corridor. The apartment is well located for either walking into the centre or getting the metro and is also well placed if you are arriving by train into Barcelona Sants - 5 minute walk away. This train station is a 20 minute journey from Barcelona airport and costs euro 2.50 for a single journey. Oscar helped us with a number a queries whilst we were there and was a great host on behalf of ralf. We would recommend staying at this apartment
