My stay at Marta's flat was nice and easy. Not much noisy and the neighbour's that I met were friendly. Antonio checked me in and gave me all the details I needed to get food and other necessities near the flat. Plus, a helpful hand drawn map! On that note, the flat is centrally located which made sight seeing easy. I used the metro to get around and as Antonio suggested, I bought a 2 day metro pass which gave me unlimited metro trips during those days. This is particularly useful while learning the metro system incase you exit at the wrong stop. So, overall the stay was pleasant. The flat was clean and I will stay again if I find myself travelling through Barcelona in the near future. Cheers!
