After reading the reviews I was thrilled to be invited to stay the night and attend a meeting at the Cosmo. But, I will not be returning any time soon. It is not a four or five star hotel. Upon entering my room I found two people there that told me they were inspecting the room and the light in the bathroom stall needed to be fixed and someone would be right up. 5 hours later and sitting in the pitch black, they finally sent someone up after a second call asking to move to a new room. The bathroom was better in the dark. In order to get to the square small deep tub, that no one could ever be comfortable in, you needed to walk through the shower which by that time was slippery and dangerous. The bedroom area was "Gothart"...that means SMALLER than my dorm room at college. There was a red stain on the floor by the bed that made me very uncomfortable. I must say that the service was wonderful and the food pretty good. The lobby is noisy and so was the room....all night long, with the patio door closed I was woken up by sirens and beeping horns. I could not wait to return home to get some rest and take a bath. This hotel must be paying off websites to list them as the best. Now, if I were 21 and wanted to have a party in a Las Vegas hotel room, this might be my choice, but I would check into another hotel after to sleep and clean up.
