We stayed 2 nights at The Cosmopolitan and we were pleased since we arrived.
The ladies that did the check-in & check-out were amazing, very kind, polite and helpful.
We stayed with our 2 kids and dog in a one bedroom suite with fountain view and the room was perfect. With a very large living room, little kitchen, a very large closet to fit all our stuff, a big bedroom with a super comfortable bed and an incredible bathroom with shower and hot tube with the Strip and Bellagio fountain view.
I also ordered a cake for my husband's birthday and requested to deliver-it at 2pm. They were perfectly on time, the cake was really good (we were just missing candles).
Our dog also had a Bark Box, with some treats inside, a plastic water bowl and a ball to play. The hotel also has a small pet park.
They also allowed us a late check-out without charges and it was really appreciated.
We definitely can recommend the hotel to any couple with kids.
The four star is because the room will need a little bit of an upgrade with the furniture that looks older and less modern than the rest of the hotel.
