Amazing. Absolutely worth the price. A bit of a walk to the metro, or to the downtown areas, but due to the nature of the trip we welcomed the stroll. The little details made the room very welcoming (heated bathroom floor, robes and slippers in the room, coffee, water, tea, real teaspoons provided and refreshed daily.)
Lobby bar/restaurant was open 24 hours and a fine/reasonably priced option to have a jetlagged first meal in the middle of the night.
The (included) spa was also lovely, several different sauna and steam rooms, large pool, many hot tubs. Weekend got fairly crowded, with an excess of drunk/inconsiderate spa goers, but that seems a minor inconvenience compared to how great the whole stay was.
