This particular five star hotel is located just 5 minutes walk from Frankfurt train station and 10 minutes to the city centre. The atmosphere is really dark and sophisticated, every forniture and decor has a unique design, from the armchairs to the chandelier. Rooms are dark as well, with elegant and comfortable beds, lcd tv screen on the wall and a big bathroom with a huge shower stall. The staff is really helpful, nad they ready to provide you with anything you shoul have forgot.
In my opinion the best part of the hotel is the stunning spa at the upper floor, equipped with steam and turkish bath, jacuzzi pool, water massage beds and also with a modern gym.
If you want some fun, the bar is a nice place to have few drinks after dinner, mostly on thursday or friday night when is really packed. Be aware that in the bar smoking is allowed, so don't go there if smoke annoys you.
Special mention for the breackfast, it' s a bit expensive (23 euro) but there's a big choice of food, sweet or salty as you prefer.
