We had a fantastic stay at Casa Alfonso. The apartment is intriguing , very tastefully done and even more amazing than the pictures. There were little touches in the apartment that we loved. The host was very gracious , received us personally and was very helpful. He even offered to let us keep our luggage at apartment post checkout. The host shared tips on nearby cafes, metro etc that was very helpful. The location is fantastic and very well connected. Loads of cafes, restaurants nearby. In fact we found a wonderful vegan place(Superchulo) just 100m from apartment. I recommend Casa Alfonso whole heartedly and thank the host for a wonderful time in Madrid.
