Bristol Luxury Collection Warsaw review: Booked 5 nights under 2 separate reservations, 3 nights paid cash and 2 nights with certificates. Booked basic room (although nothing is basic in this 5 stars hotel), applied for NUA, NUA cleared an upgrade to the deluxe suite (1000sq ft) for the entire stay. I am Titanium. Very warm welcome from the front desk at our arrival. The suite was great. Super comfortable bed and top quality sheets (I’m a snob for sheets!). Housekeeping twice per day. Breakfast is complimentary for Platinum and above and was exceptional. I will definitely go back. It was one of the best stays I ever had.
