Just stayed a few nights there. Photos incoming. We drove from Lisbon to Madrid. The rooftop bar was closed, the gym was open (but we didn't go to the gym ever). It rained a lot on our stay. Everyone was incredibly kind.
They handle the parking situation pretty well given that it's a bit of a logistical nightmare. However, it was definitely one of the least complicated parking fiascos I've dealt with inside of major city. Location - is fine. If you're into being on a busy shopping street.
Bonus points: champagne and tequila selection. Wow.
