We stayed here for 3 nights (mid-week) - the hotel wasn't too far from the train station (Centralna - we walked it, in the snow, with cases). The room was lovely, modern (we had a Maritime theme) and clean.
I used the fitness centre once - the staff there were not very friendly. I asked about the pool, and the girl on reception pointed me toward a door, so I walked through, and could kind of see the pool behind a temporary screen - but it looked like maybe some construction work was going on, so I didn't go any further. I noticed when I came back out, there was a 'no entry' sign on the door. The machines in the gym itself were good, and clean!
The breakfast in the hotel was good - a lot of choice - hot food (bacon, sausages, egg, mushrooms etc.), fresh fruit, polish food (lots of pickled things!), breads, pastries, cereal etc. - plus a coffee machine. Also, you could have an omelette cooked to order.
The hotel is also only about a 15 minute walk from the old town, and even though we experienced sub-zero temperatures, it wasn't too bad of a walk.
The only negative I really have to mention, is the poor design of the shower. It looks lovely, and is very modern and clean, however, there's a small gap under the shower glass, that allows a LOT of water to get on the bathroom floor. However - easily mopped up with a towel!
