Charles and Giselles apartment is a very spacey accomodation in the very heart of Madrid - it couldnt be more centric! Due to the location it is a little noisy outside, but thats pretty normal when you live close to Sol. The room was totally fine and the bathroom as well. It was no problem to check in even though we arrived very late. There is not much talking with the hosts or other guests but you're always being helped in case there are questions. I can recommend it!
