Mercedes' house is not to be missed as location, location, location in Barcelona. Opening onto the rooftop terrace of the amazing Plaza Reial and just off La Rambla the house is in the middle of the Barcelona universe and it is possible to walk everywhere. The rooms are quaint and quirky which is half the fun (As Mercedes says, "This is Europe.") but our every need was catered to in a most thoughtful, caring and unobtrusive way. The house is organised very intelligently to make her guests feel at home and included but also private. She even provides a jug of sangria or wine every evening for the guests to enjoy as and if they wish. We loved our stay, took advantage of her wealth of knowledge about the city and really enjoyed having Stevie the golden retriever to pat and fawn over. We thoroughly recommend Mercedes listing and can't possibly imagine how you could stay somewhere better. Be aware that there is no lift and there are five storeys to get luggage up but it is worth it, believe me. We had a fantastic time!!
