Sol is a great host and I really enjoyed my stay there. I didn't feel like a guest, I felt like I was her long term roommate. She even helped me with tips how to improve my Spanish and Portuguese. Location is excellent, away from noisy and touristy Madrid, but still close enough. Walk to the center is the best part as you can take different routes through Malasaña - in my opinion the most interesting neighborhood in Madrid. WIFI works well and location is extremely quiet so I could work and rest after exploring this amazing city.
