The Kristian’s place is very central area of Madrid and you can get any major city attraction within 10-15 minutes of walking. Although it’s middle of the city, the area seems safe and “mostly” quiet, but it is still the center of city, so sometimes it gets noisy at the middle of night. The place is not huge and sclean and well equipped. Self check-in/out is very easy. We stayed only 1 night and Kristian’s place was perfect for the short stay.
