Mariano's place is simply awesome. Hip, clean and it makes you feel like you belong there. I strongly recommend it to anyone who wants to visit Madrid and have a bit of fun in the super-friendly Malasaña. As for Mariano, he is a legend. Friendliest AirBnB host I've met by far. If you're planning to visit, please make sure you consult his local expertise, as his recommendations were always 10/10.
