We arrive at the room with an intense odor and two big machines running. Reached out to host and received a reply basically saying they cannot help me and that I would need to figure it out with the Vdara staff. Called the staff and they mentioned that they don’t handle it so I was not getting anywhere with both the host and hotel. Then I realized the tv didn’t work as well when I tried to turn it on to unwind. Per host, they advised mngmnt and they will reach out first thing in the morning but I did not get a txt or call the next day. I had to reach out again but did not get any response anymore. It was only after I let them know Vdara’s technician came to check on the tv and they advised they can’t fix, was when I got a response. That’s when I found out there was a major leak that happened prior. The technician also commented there was a strong musty/mildew smell. We had our room changed with no help from host. We realized we slept in a room probably not safe to sleep in
