A modern, to very appealing building but very good location, 5 mins from downtown but in much quiter area of the city, with a large park nearby -great for jogging- and one the the best hotel fitness centres in Warsaw, with swimming pool, hammam and all machines you can dream of.
Restaurant wise the choice is limited with one italian, rather plain restaurant but few nice places nearby (Belvedere, Sowa & Friends, Rozana, etc) - all in, a nice place to stay at (and if you have time, you an rent a well equipped bike and enjoy a bike tour)

Hyatt hotel offers everything what you would expect from a premium hotel.
It had great and comfortable rooms, spa, great food and the location is perfect for a quick tour around the city center on foot.

The rooms are clean and decorated with good taste.
Mini bar however was extremely expensive with snickers foe around 10 euros, but it is optional so no need to use it.

breakfeast is includen in your stay which is great and tastes delicious (standerd selection).

Overall a good place to stay is you seek comfort.

Hotel have got nice location but the price is too high for that standard ... Hotel restaurant Venti Tre have got really good food , Łazienki lobby bar looks really nice but casino and pool is not really good. Service is poor .Hotel is not really bad but at this price i recommend Intercontinental . I stay here just because the conference at the same hotel but Westin or Intercontinental is much more better

The Hyatt has everything you want including a good central location but no soul or character . the rooms were adequate . the packed breakfast was a complete rip off at €15 for a few very average items . I could not believe the high internet price . Would not stay again
