Myrian was an excellent host during our stay in Madrid! She was very welcoming and she treated us like family. She gave us various suggestions of what to visit and how to get there. The apartment is not in the center of the city but there is a metro station very close by, making it very easy to reach the center (it's cheaper to buy a ticket for 10 trips btw). The room is very comfy and you even have your own bathroom. I would definitely recommend staying with Myrian and her family!
