Staying here for two nights, booked classic room through beatthetimer - only one suite available on arrival, and was lucky enough to get upgraded to that one: the Presidential Suite (also called the Wawel Suite).
It is an amazing suite. It is more than 100 m2, and have striking views towards the river and the castle.
It have a small kitchenette with good quality machines from Siemens, a large living room with a huge sitting group, media center from Bose, barista machine, dining area, various pieces of art.

The bedroom is large as well, it feature a walk in wardrobe with make up mirror (it is separated from the bedroom), a terrace and a nicely appointed master bathroom with Molton Brown amenities - there is a jacuzzi and a separate massage shower cabinet. The toilet is also in a separate cabinet.
