Mercedes was a great host and was incredibly knowledgable about Barcelona and the places we should check out. She immediately took us up on the terrace and marked out a map of the area. The bed was super comfy and her apartment in general was very unique and located in a very convenient spot. We just so happened to be there during the festival of Sant Joan and were able to relax on the terrace while fireworks went off from everywhere, even right down in the plaza! It was truly awesome!
