The apartment is small but really charming and has everything you need for a long weekend in Madrid. The hosts are really nice, helpful and easy to communicate with and the possibility of them leaving the keys for our late night arrival was really handy!
Some necessities (such as toilet paper, coffee and coffee filters) were provided, but the amount wasn’t sufficient for more than a couple days. So if you are staying longer, it’s good to be prepared to buy these yourself.
