Carlos was an good host. The flat itself is simple but it has all the basic stuff. Not big, but big enough for us, a group of 4 people. The location was very central and in walking distance to all the main spots of Madrid (except Plaza de Toros and the Santiago Bernabeu Stadium).

Not terrible, but worth a comment: We came in to the flat at late night and there´s a 20€ fee for that, which I cannot understand why, since the host lives very near to the flat and we didn´t use his time (or his flat, although we´ve paid for it) the whole day.

Overall, i would recommend it!!
