Staying at Elke and Steeve's place was really great. They were both very friendly and relaxed, and their apartment is nice and clean. The room was small, but just perfect for us, and the bed is comfy :) I would recommend bringing earplugs and warm pajamas - the apartment is a classic, Southern European one with thin ceilings and no heating, that's just the way it is in an old neighborhood like Raval. Really, the place is wonderful!
