Had a lovely time staying with Mercedes. She is very easy going and very helpful with lots of tips of places to visit that tourists don't normally see. The bed was very comfortable and the location can't be beaten. The only downside I can think of is if you aren't good with stairs as it is about 6 floors, but if you can manage that then it is worth it as you can have breakfast on the roof with lovely views of Barcelona. If we ever go back, then this is where we would stay. Thanks, Mercedes and Stevie (Wonder)!!
