No complaints.....the hotel is under renovation and they removed the laundry facility...dilemma. So I started to search yelp and found reviews to 24 Hour Laundromat Twain....it's true, the area is not that great but you should be fine.
The woman (whose name I didn't get, drats!) working was so nice. I had no idea how it worked (did they use tokens, cards or coins) she showed me the change machine and gave me soap powder (it's true, it's free!). It's a Laundromat, so there are different sizes of washers and same sized dryers. They do the job. I did my yelp check-in and got my quarter (equivalent to 9 free dryer minutes).
Next time I'm in Vegas and need to wash, this is where I will come!
