This place was one of the best places I have stayed in Madrid. I highly recommend this flat on a few reasons.

1. Kristian is excellent on communicating right away. I.e. I checked in at 1am and couldn't locate the key but he quickly responded and helped me
2. location is very close to everything in Sol. Only 5 minutes away from Sol station and attractions
3. the place is very clean, tidy, and a lot of space.
