We had a great time staying with Marian and Juan Gabriel. When we checked in, they also gave us an introduction to Madrid, complete with a Google map and trello board detailing their suggestions on where to go and what to do in the city. We used these resources throughout our trip! The room was comfortable and sunny, and the entire flat was beautiful. It was the first time I slept on a futon, and it was surprisingly comfortable! Also, the flat was in a great location to explore the center of Madrid. We walked everywhere, including to and from the train station when we arrived and left. I highly recommend staying here!
