Jordi is very friendly and answers your questions very fast.
The room and apartment is small but cozy, like he discribes it and perfect for a few days in Barcelona.
His apartment is near a metro and bus station.
The Sagrada Familia is only one metro station away or a few minutes by feet, if you want to walk. Within a 30 minutes walk you can be at the Casa Milá and the Casa Batlló or at the Parc del Guinardó.
