Esthetically, the Cosmo is the coolest looking casino on the strip right now in my opinion. But its service is hit and miss. The valet was fast and very friendly, the friendliest employees we met all weekend. Front desk was fine, not overly friendly but not rude, either. Our room overlooked the Bellagio fountain for a $25 charge and the room itself was gorgeous. However, we were charged $5 for a soda we didn't even drink, it was already missing when we came to the room. Our bathroom light was burned out and the air stayed at 75 degrees and wouldn't change when we tried lowering it. We told them about it and no one came to fix it. The weirdest thing was someone knocking on our door like a madman at 9am and then using their key to come in WITHOUT saying that they were housekeeping or anything. Luckily, we had the additional door lock on so that they couldn't open the door completely, but instead of wait 30 seconds for us to get to the door, they just left. I still don't know if it was someone who worked for the hotel or some random person who had a key to the room! \n\nI also sent an email asking to fix an account issue with my Identity membership. It took them five days to respond and they said they didn't see any problem, but I logged in and it was still there. I loved the view and look of the Cosmo, but service was extremely disappointing considering there are so many other places to stay on the Strip with excellent service.
