As with other travellers, we really enjoyed our stay in Madrid which was greatly helped by the central location. Even though I was later than expected due to missing a train, Sol kept in touch and her friend let me in at 00:30 which was kind. She was very welcoming and gave me recommendations. The street is just off the main road by the Royal Palace but quiet so you can enjoy the sights and get a good night's sleep. The only thing we didn't like was that the flat was smaller than we thought, with a slanted ceiling we had to keep ducking under because of the folded out sofa bed. Overall, we would stay there again but preferably with two people instead of three.
