Confusingly, the Chopin Apartments is a separate company that rents apartments in the Platinum Towers, so the front desk at Platinum Towers cannot generally help you out. No complaints in general with Chopin Apartments company, they were helpful for what it is.
The good: Clean 1BR 1BA apartment with Free WiFi, full kitchen, and laundry. Chopin Apartments sends someone to neaten up your apartment and give you fresh towels, soap, toilet paper, shampoo every day. Kitchen has two bottles of water and some coffee and tea.
The bad: My apartment did not have Air Conditioning in 90-deg weather. Apart from hotel amenities mentioned above, not much else (like q-tips, tissues). You can use Hilton's Gym/Pool/Hot Tub (a 10-min walk) if you want to pay an extra $12 USD for each day-pass that you have to pick up at Grzybowski 43A (15 min walk).
