Severine and Angel's place was everything we expected and more. having walked around the whole city I probably wouldn't have chosen a different location for a short stay. You are right in the middle of the most atmospheric part of Madrid - a 2 minute walk from the Royal Palace, and 1 minute walk from Plaza Mayor and Opera.
The apartment is super clean and extremely well fitted out - the new spacious bathroom, and an extremely functional kitchen with anything you might ever need!
The hosts were superb at making sure your stay was a success - lots of information for you to go through and since they couldn't be there themselves their cleaner showed us a couple of short videos explaining everything you need to know about the apartment.
if you leave the front bedroom balcony door opened you can hear street nosies (though it is not a busy street) but this is Madrid for you - it is noisy and vibrant. You can always keep the balcony door shut and have the aircon on.
the best airbnb experience we have had so far.
