We stayed at Sergio's place for 5 nights during New Year's eve holidays. We were 3 and had a wonderful time! Sergio was not there when we arrived so he arranged so that we could get the keys. The place is great. This is as described, if not better. It is nicely decorated and his place offers all the comfort needed. It is also conveniently located with easy access to metro and plenty of places to have drinks and food around. It was also easy to set up heating at the right temperature. Sergio even left the Madrid Lonely planet Guide that we could use when we were there. I highly recommend his place to anyone looking for a nice, clean and comfortable place to stay in Madrid.
