Wonderful location, close to La Rambla and the Gothic area. Please be aware it is a bit difficult for tall people as the apartment is an original, with very low ceilings and door ways. Plus the 109 steps, a bit hard with bigger bags, but we made it. Note that you will here the nearby disco from your room until 5 am. We slept through it ok.
Mercedes makes a great Sangria daily, take care it has a kick to it. She is warm and welcoming, even pulling out the cactus thorns from my husbands shorts when he offered her some help moving things around.
Place is very small, but fine for a few nights.
