Josep's place was an absolute delight to stay at for the week we stayed in Barcelona. It's located in the Sants area which is close to a metro station and many bus lines, though not centred right in the downtown area. For us, we enjoyed the location being a little quieter and close to lots of great cafes and shops including the famous Sants Market just around the corner!
Josep was very helpful and left a detailed book with all the questions you'd have about the apartment (washing machine, dishwasher details etc) and lots of fantastic restaurant recommendations.
The space is clean, modern and very cozy. We had a great stay!
