I had a wonderful stay in Al's place. Although I didn't meet Al in person, he was quick to reply my messages and was positive on every request I had. Uri who is keeping the flat is very modest, I hardly noticed his presence and never had any issues. The flat is located just 200 meters from Paralel metro station Line 3 that is very convenient for the main attractions and Sants train station. The Rambla and the harbor is around 10 minutes by walk. The kitchen is very handy. After 7 days of my stay it truly felt like a small home away from home.
Advice: if you are light sleeper, bring earplugs because the neighborhood is loud till late, especially on weekends.
