Great host, very friendly and knowledgeable of Madrid.
Well connected location to public transport. Not much to do in the immediate area, but it is a 5 minute walk from the metro, and only a few metro stops from the centre.
This place is great value for money. There is a supermarket just up the road, which was very handy and we even cooked dinner one night when I wasn't feeling well.
The bed was comfortable, a little bit noisy at night time out the window, but it is much quieter if this is closed.
We felt very welcome in Ivaylo's house.
