Place was immaculately kept and in a great location to explore Madrid.
No site we wanted to see or restaurant we wanted to eat at was more than 2 miles away, all walking.
Surrounding neighborhood has some amazing restaurants around it that aren't crowded because the area is far enough away from sites and parks that crowds don't enter the area.
The inside was comfortable and bed one of the best beds in an Airbnb I've slept on, and I'm picky about my sleep.
Place is dark and surprising quiet from street noise that's right outside the two windows. The only nitpick is the walls are thin in building and you hear every and anything, but that's not on the Host and the place is worth every other "pro" for that one very "semi-con."
