Hotel is very hip and contemporary. Would give it 5 stars if it was on the strip. Very trendy with good coffee (Perqs) in lobby. Mcdonalds, Starbucks, and Walgreens across street. Easy access to strip. Quick and easy check in. Line is long at check in time but that's to be expected. Clean lobby and common areas. Lots of slots. There are several popular food places in SLS and they are Bazaar Meats and Umami. Didnt get a chance to check them out though. A friend of mine went to Umami and he said it was outstanding.
All in all SLS is outstanding. Only drawback for me was that it wasn't on the strip. But if you don't want to be on the strip but close to it, this hotel is a 5.
