Kristian's apt is situated in the center and is very convenient to accessing many Madrid neighborhoods. There were a few cosmetic issues that we addressed with Kristian, and I
think he will tend to them. He was not in town when we were in the apt., but he responded to our written communications. There was a little noise, but being right in Sol i think it would be unrealisticto expect perfect peace and quiet. With windows closed, sleep was fine. All in all, recommended for your stay in Madrid.
