I was two hours late from my planned arrival time due to a business meeting (a bit of miscommunication there as it was approximate and out of my control) but Luis was very responsive (100% response rate is accurate as he was on top of things and this made it very easy to coordinate with him) and made sure his cleaner was waiting to let me in. She gave me a very warm welcome and showed me around the flat with a smile despite that she had to wait for me for two hours. Location was perfect as its right smack in the middle of the city so you could pretty much go to any neighborhood you're interested in. The flat was clean and had AC and wifi. I would highly recommend anyone who is visiting Madrid to stay here.
