The most important aspect of this Air BnB to know is that it is in downtown Las Vegas, in a neighborhood that locals would describe as sketchy to gentrifying. I have stayed at other Air BnBs in places such as Los Angeles that are in comparable areas, and I never felt unsafe here. I mention it only because anyone considering this unit should be aware they would be less than a mile from the Fremont Street experience, the classic part of Sin City, in a residential area that tourists do not usually come to. There are funky little restaurants opening up within walking distance. So this is close to the places you want to see, but it is a block that nobody except residents likely come to. To reiterate: it's fine. Do not worry unless you are anxious about being downtown, in which case that rules out lots of options. (It's different, too, in the way Las Vegas is different. I'm not used to bright sun, wide streets, and suburban style for a block such as this.)
The next thing to know is the units are cool and funky. Care and cash went into the themed renovation(s). I tried two (I was headed out from LV and then back, so this was the home based for a longer trip): one looked like an early 1960s bachelor pad, the other like Ken and Barbie's honeymoon suite.
The keys are an August digital lock. If you don't know about these, basically it has either a code you punch in or an app that connects via Bluetooth. The reviews are right: this is not an improvement on a physical key. But I see why for Air BnB it makes sense, because it eliminates all issues of coordination and timing. The system works flawlessly too, once you figure it out. Just download the app and read 1 minute of instructions.
The host is prompt, responsive, considerate, and easy to work with. If I were looking for a place in Las Vegas, not attached to casino, I'd come here again without hesitation.
PS I'd rate this as in the top 20%, maybe top 10%, of Air BnBs for how well stocked with linens and toiletries. Also soft drinks and a bit of booze in the frig, with a note to help yourself.
