My stay at Daniel's was wonderful! His place was very clean and Daniel himself is friendly and attentive--everything you look for in a host. It's less than five minutes walking to the La Latina metro stop. La Plaza Mayor, Sol, and El Palacio Real are all within reasonable walking distance. Great neighborhood to be in, although some nights may be a bit louder because it is, in fact, a lively and happening place to be. Definitely best suited for a single guest, however two could be doable. I highly recommend staying with Daniel, I would definitely try to stay with him again if I ever go back to Madrid.
