Let me first off say that I usually stay at hotels on the strip and have never stayed in downtown LV. I was on a road trip with a friend of mine and were booking last minute places to wherever we decided to head to next. Knowing this, we booked Roey's place and he was always great communicated back and forth any troubles we faced during our stay. That being said, here is my honest review.
Neighborhood: It is located behind a mexican supermarket in a neighborhood that does not exactly feel completely safe. There are kids and teenagers walking to and from school, however when we were driving to and from the house we saw homeless and "sketchy" individuals.
Location: It's close to some really cool places. If we did not stay at the house, we would have never discovered some hidden treasures in DTLV. Ferguson's downtown is this ecofriendly, cute shopping area with amazing coffee and local shops (highly recommend!). It is also close to downtown LV if you want to participate in some cheaper gambling and other typical Vegas entertainment.
Overall: I most likely would not stay here again on my next LV trip, however it is cheaper than most hotels and after adjusting to the neighborhood, it felt relatively safe.
