A proper hotel with beautiful exterior and interior. It's been there for quite a long time, in the busy Gran Via, but the rooms are modern and functional incl. heating (essential in December), a fridge, foreign (ENG GER FR) language TV-channels, etc. I was missing a kettle but it would have been provided had I asked.
I would recommend to opt for the in-house breakfast because of the good choice of items, even gluten free bread (available by request). One can decide from day to day to have it or not, for a reasonable fee.
