A gorgeous apartment in a wonderful location - so close to everything. Sparkling clean with everything you need (including great air conditioning, a must in the Madrid summer). Christian was very easy to communicate with, prompt to respond and offer assistance if needed. Highly recommend.
If you are a light sleeper you might be a little bothered by noise from the street and surrounding apartments but I don’t think it would be possible to be somewhere so central in Madrid and not have a little street noise - it’s the nature of the city!
