"My stay last week."

I enjoyed my stay on April 11 13. The workers, from the front desk to housekeeping were professional, helpful and friendly. My bed was very comfortable. Housekeeping was attentive to details by placing things where they were supposed to go, like the coffee machine, the bath towel I wanted to reuse and the ironing I board that I kept out. The hotel was clean and nice to look at. The conference rooms were easy to get to from my hotel room in Tower 3. I can say this is the best hotel I’ve ever stayed at. I have stayed in many hotels. I would recommend Hilton Union Square to my friends and family.
