Hector's place is about 25 mins away from La Rambla street by walking. It's also two blocks away from Plaça d'Espanya, Barcelona which is a subway hub. There are many cafes and restaurants around.
The room I stayed was a small room with a single bed. It shouldn't be a problem for travelers who go out early come back late like me. Hector also lets you use the living room area which is great if you want to watch tv and chill. On top of that Hector is a very nice guy and easy to communicate. I recommend his place.
