Best location in Barcelona!
From Marc's place, you will be walking distance to basically everything you need in Barcelona. Comfortable, safe, clean place with a gorgeous view and right in the heart of the city. Close to train and metros, shopping, and amazing food.
I was concerned about previous reviews and the upstairs bedroom. I am 6'3" and o issues with the bedroom, it was fantastic. The shower is the only part that isn't really functional for taller people but luckily there is a full sized shower downstairs.
Definitely would stay here every time I come to Barcelona!
