The unit was very clean and roomy. The bed was one of the most comfortable beds either of us have ever slept on. The neighborhood was fairly nice, and we felt safe the entire time.
Check in was great, there was simply a lock box left with a key for us to use. We didn't have to coordinate anything with the host. He provided us rental bikes to use to get to and from Fremont street. That bike ride was roughly 10 minutes each way. It is kind of hilly though, so keep that in mind if that's what your plan is.
Be warned, there are skylights in the unit. This was a surprise to us when we arrived. Waking up early is about the last thing I want to do in Las Vegas. Luckily we had dark bandannas to cover our faces, however I know we would have slept much better if we could keep the room dark past 7:30AM.
