This was the first time staying at the Cosmo and we were extremely excited.  Man, this place did not disappoint.  I've read some other reviews about customer service and issues with room keys, housekeeping, etc and for the most part, I would say our experience was a lot different than the negative ones seen in other reviews.\n\nOur room was beautiful and clean.  We somehow scored a room on the 51st floor overlooking the strip.  Our terrace view was epic.  The terrace was the biggest selling point for us.  The bathroom was huge and contained a large walk-in shower and a soaking tub with a window that overlooked the strip.  The sleeping area was nice and the bed was super comfortable.  The sitting area was huge and had a couch, desk, minibar, sink, big screen TV and dishwasher, which we found random.  The closet area was huge and the iron worked well.  Safe worked well too.  There are random books placed throughout the room, which were pointless to us, but a neat way of being different.  I love the lighting features of the room.  By pushing a button on the phone or by the entry door you can control all of the lights in the room.  Great way of just laying down, hitting a button and going to sleep.\n\nThe hotel as a whole is beautiful.  Completely geared to 30 to 40 year olds with a lot of modern flare and chic details.  The check-in area is fun with huge LED columns that change constantly.  There are lots of restaurant options.  We've eaten at Henri and Comme Ca, which were both great.  Bond bar is fun late at night with interesting drinks and go-go dancers shakin' it above the crowd.  Light system in Bond is great!  We didn't make it to Marquee, but from what we heard and saw, it's THE place to be in Vegas right now.\n\nWe only went to the Boulevard pool, but it had a neat vibe.  You can play pool, Foosball and PS3.  Drinks at the bar are pricey, but that's pretty much anywhere you go in Vegas these days.  Get there early for a lounge chair, otherwise, there really are not many places to sit unless you want to spend the coin on a cabana or daybed.  Have Tyler make his ginger mojito.  Fantastic!  Music could have been a little louder, but it was nice.\n\nNow, here are a couple of the challenges we ran into.  When we checked in, the original room faced the mountains.  We waited a couple hours for a different room and like I said somehow got that great view on floor 51.  The problem we ran into was, they had given us our keys and said they would be activated when the room was ready.  Upon receiving the phone call for our room we entered the elevator, put our key in to access the floor and the key did not work.  Someone else had activated floor 51 for us.  When we got to our room, the key didn't work.  We had to go all the way back down to the front desk to get new keys.  They fixed it for us right away and the key worked fine.  The card readers in the elevators are a little goofy, but you'll get the hang of it.\n\nI think the biggest downfall to the Cosmo was the housekeeping.  Yes, our bed was made every day and the bathroom was cleaned as well.  The garbage, however, was not emptied daily, and I do not believe the ice container was cleaned out.  The mini-bar was not replenished during our entire stay, but that wasn't a big deal since we didn't use it much at all.  Also, when we first arrived in our room there was a large wet spot on the carpet just outside of the soaking tub.  My guess is that it was used shortly before we checked in and the room was cleaned.  The terraces are also not cleaned daily.  I used a glass for cigarette buts and it wasn't touched the entire stay.  Also, found a used condom on the terrace, which was thrown from above I'm sure.  That wasn't cleaned after we returned back to our room.  Otherwise, everything was very upscale.  I think people need to remember this is Las Vegas, so crazy stuff is bound to be found and happen.\n\nWe had a light burn out in the toilet area of the bathroom.  I called to have it replaced and when we returned to our room it was done.  Overall customer service was good.\n\nShower could have had more water pressure.  I think that was my only real complaint.  \n\nThe good of this hotel far outweighs the bad.  If you stay there, get an Identity membership.  Its good for all your gambling, food and shopping purchases, as well as your hotel stay.  By the time we left after three and a half days, people knew our name and we are by no means heavy gamblers or big spenders, so that felt nice.\n\nThis is my new favorite place to stay in Vegas and probably one of the best hotel rooms I've ever been in.
