Nice stay with no issues!

JohnnyI0695 (Seattle, Washington) on Jun 20, 2026

After reading some of the reviews, I was a little nervous as to what to expect here. I even considered changing hotels, but just decided to go for it. To provide some context to my experience, my stay was mid-week from Tuesday to Thursday in mid-June. I was in a Terrace Studio king bed suite on the 38th floor (not a fountain view). This was my first time staying at Cosmo. I checked in at 12:30pm and my room was ready right away. The front desk agent was pleasant and provided a quick overview. I really looked hard for wear and tear in my room and found next to nothing. There were no maintenance issues at all. The room was spacious, clean and the balcony was very enjoyable for morning and evening relaxation. The housekeeping staff on my floor were extremely friendly. I did not need to request anything via phone or at the front desk, nor did I try room service. I really enjoyed the location of the hotel and the varied options for food at all price points. The Chelsea pool deck was nice! Check out was easily done via a QR code or an email link. Overall, I luckily had a problem free stay and was pleased with the room and all the experiences I had. I would consider the Cosmo again for future stays.

Hotel had used dirty underwear in the room. Concierge was notified and we were told a manager would be calling us and no one did

I am writing to express my disappointment regarding my recent stay at your hotel. My family and I paid $3,127.66 for our stay and expected a clean room and professional customer service. Unfortunately, our experience fell well below those expectations. Upon arrival, we discovered a pair of used, dirty underwear in the bathroom. In addition, there were dust bunnies present on the underwear indicating it had been there for a while. The bathroom walls were visibly dirty and had not been properly cleaned. Finding another guest’s personal item in our room was both unacceptable and concerning, as it raised questions about the overall cleanliness and housekeeping standards of the room. Prior to our arrival, I also contacted reservations seeking assistance with either an early check-in or adding an additional night due to our early morning flight. During these calls, I was disconnected twice by reservation staff and was unable to receive the assistance I needed. It took well over a hour to get help. This added unnecessary frustration before our trip even began. Given the amount we paid for our stay, I find the condition of the room and the level of customer service we received to be unacceptable. I would appreciate a response regarding how this situation will be addressed and what steps will be taken to ensure future guests do not have a similar experience.

Personal touch (GONE)

Boy G (Phoenix, Arizona) on Jun 18, 2026

Lack of attention to detail has really become evident at the cosmo. I booked my stay at the cosmo 3-4 mos in advance and requested the high floor terrace one bedroom fountain view for my 40th anniversary. (Did not happen). Ended up with a city view room with so many problems (to many to mention) but I will, and will tell everyone I talk to as well. The room was in sad shape.(1)When you would open the shower it sounded like a freight train in the room. (2)faucet handle on the sink would not turn on or off (just spins). (3)Body wash dispenser empty-No kleenex tissues in dispenser. (4) 4ft rip in the terrace drapes. (5) Ice machine has out of order sign on it for my entire stay (4days) The complete 52nd floor with no ice and no way to get it from another floor. Numerous calls to the front desk went without concern. Doubtful I will stay again even though mgmt has already offered a 4 night comp stay because all I heard was Im sorry for the poor experience we were having at the cosmopolitan. Our stay at the cosmo for our 40th anniversary was supposed to be a great experience for my wife and I, friends and family and the personal touch and lack of attention ruined it for us. PS> This experience inspired us to update our cesars rewards cards.

Rudest employees of all casino properties I’ve ever been to.
