Staying in Fernando's place was very convenient for my parents and I! Location is great - its super near the metro - Callao station (literally 1 min away) on Gran Via and it was a great base for us to explore Madrid. The check in process was smooth and someone was there in the apartment waiting to welcome us. The Airbnb had great views and was very clean and spacious! The only thing I would say is that there is only one aircondition in the entire place and it was very weak. We stayed in the summer in August so it was very very hot. Fernando had a fan but only in the master bedroom and the common / sofa bed area didn't have any and we were constantly sweating. Overall we still had a great time at Fernando's! :)
