My partner and I stayed at Mercedes' apartment for 3 nights and it was the perfect location/base for staying in Barcelona. The famous La Rambla was only a stone's throw away and the Placa Reial Square is beautiful, surrounded by palm trees, a fountain, Gaudi-designed lamp posts, and many restaurants. The room we stayed in (room 1) had its own bathroom and outdoor shower (which adds to the experience!). Mercedes was a lovely host and gave us a bottle of red wine on our first night and let us eat our dinner on the rooftop terrace overlooking the plaza. Her dog, Stevie Wonder was also delightful and adorable. I would definitely stay there again!
