Antonio was a fantastic host! He was very flexible with our flight times, communicated well even before my flight (providing transit info and directions from the airport). While there, we could easily get ahold of him within only a few hours. He suggested great restaurants and attractions as well as explained some of the transit tricks to get around.
The home was just as delightful. It was more than enough for my group of three, and could easily accommodate 4/5 people in a pinch. Centrally located, we were able to walk to La Sagrada Familia and a couple other sites as well as several metro and bus stations in order to travel around. Highly recommend the Born District for shopping, El Reval for a drink at Bar Marsella, and Can Paixano (La Xampenyeria) for Cava and Entrepanes.
