Hello everyone!
Staying at Gianluca's was a smooth experience. The home is 1 min walk from the Metro station across the Main Street. It has a supermarket across the residential street (not open too late). I didn't find the home hard to find (I didn't have a phone with me and it was still easy to find). We met his friend who gave us the key. They gave us 2 sets of keys which is cool. The home was as pictured. My friend and I were comfortably able to walk to Las Ramblas and the Gothic Quarter. And in the other direction one can walk to Plaça Espanya which has the mall that used to be a former bullfighting ring, the fountain and MNAC museum. Then you can use the metro for everything else or rent a bicycle (we did both). Only negative thing I could possibly say is that the house gets a bit cold. Luca provided movable heaters which can help out with the rooms (but I don't think there were enough for every room, maybe I was wrong). I read online that central heating isn't really widespread in Barcelona anyways. The wifi could be a little stronger. And finally the checkout time is 10 AM. The home definitely has character. Overall I greatly enjoyed my stay, thanks Gianluca for having us.
