Roger's apartment has a great location. You can easily walk to the different places you have to see. There are grocery stores beside the apartment, and a lot of restaurants on every corner. They have a family-owned restaurant called La Plata just a few minutes walk from the apartment. It's been up since 1945, and it's a must-try when you go to Barcelona.
Communication with Roger is EXCELLENT! Had no troubles with him or his apartment whatsoever.
Would love to stay at his place when we go back to Barcelona!
