Entire staff from front desk to security to housekeeping made us feel welcome and our stay comfortable. The central location allowed us to do a lot over our short weekend stay. Would not skip breakfast at the Meli cafe downstairs.

I recently stayed at the Trump International Hotel & Tower Chicago, and it exceeded every expectation. From the moment I arrived, I was impressed by the warmth and professionalism of the staff. Check-in was smooth and welcoming, and I was personally escorted to my room—which turned out to be nothing short of spectacular. The room itself was spacious, immaculately clean, and beautifully designed with modern touches and classic elegance. Floor-to-ceiling windows offered breathtaking views of the Chicago River and city skyline. The kitchenette was a nice bonus and made the room feel more like a luxury apartment than a typical hotel room. The service throughout my stay was consistently excellent—attentive without being overbearing. Every request was handled promptly and with a smile, and it was clear that the staff genuinely cared about making my stay enjoyable. I also had the chance to dine at Rebar, and the food and views were equally impressive. The atmosphere was relaxed yet refined, and it made for a perfect evening. The location is ideal—walking distance to the Magnificent Mile, Millennium Park, and plenty of restaurants and shops. Despite being in the heart of downtown, the hotel felt like a peaceful retreat above the city. Whether you're visiting Chicago for business or pleasure, I highly recommend the Trump International Hotel. It’s a standout experience in every way—luxury, location, service, and comfort all rolled into one.

From the moment you walk into their lobby at the hotel, you enter a place of calm and relaxation. We stayed in a room with the Water Tower view, and if you have that as the option, take it. It was a beautiful sight to see waking up every morning. This hotel like their other properties are in a class of their own.
