Ok, if you are looking for a nice, clean, and safe place... Monte Carlo is the place to stay. And if you want to stay at a super central locations... this is the place.
Nothing is fancy at the Monte Carlo, you can't brag about that, its not Bellagio or Mandalay Bay but its inexpensive and the hotel itself has everything you need right inside, even a tram that will take you from the Monte Carlo to the Bellagio, with a stop at the Aria.
The staff are friend and very helpful when you have questions or concerns.
