Pros:
+ Beppe was a very good host. He was punctual, gave us tips on what to visit and made us feel welcome.
+ The apartment had all necessary amenities
+ The location was great: no noise during the night, close to Camp Nou, very close to the local market (which I recommend for), close to the Montjuic fountain and very close to the metro.
Con:
- When I visited, it was really hot in Barcelona, so it was also pretty hot in the apartment too.
Conclusion: Beppe's apartment definitely has my recommendation!
