Moon was absolutely beautiful and very comfortable for my wife and I and her parents. The two bedrooms each have their own bathroom (one has a lovely spacious two-person tub) and doors for complete privacy. Each bedroom also has its own AC control. The entire apartment is lovely and very welcoming. Very central and walkable to everywhere we wanted to go.

Note that although there is technically an elevator, we were advised not to use it because of potential breakdowns. The apartment is on first floor (second floor to US-ians - remember that the ground floor is "0"), and there are 15-20 steps to get up to it. Something to be aware of if you are traveling with someone with bad knees as we were.

We would definitely stay again if we are lucky enough to be back in Madrid!
