I stayed in Andy and Briar’s casita long-term (1+ month) and the entire time was a great experience. The casita has everything one would need for a short or long-term stay (e.g., very comfortable bed, hot water with strong water pressure, coffee machine, fridge, microwave, plenty of storage space).
Andy and Briar are gracious hosts and are always happy to share a drink if you are interested in company and conversation. If you just want to be on your own that is also no problem. The casita has its own entrance and you can easily go in and out without seeing anyone.
Even though all stores you would need are a short distance away (Vons and Target are walking distance), I would advise a car if you stay here. The Strip is also very easy to get to.
I fully recommend Andy and Briar’s Casita to anyone visiting Vegas with a car. If I wasn't now living in Las Vegas I would definitely plan to stay again!
