Time Out says
Budget Suites is perfect for visitors planning on staying in Las Vegas for an extended period and requiring some self-catering facilities. The daily rates are nothing special, but a one-bed apartment can be rented for around $250 a week, with further discounts for monthly rentals. Each secure 220- to 300-unit complex is made up of basic mini-suites, all with their own kitchen and bathroom. Maid service is available, but you can save on the expense by bringing your own linen and towels. There are four locations dotted around Las Vegas, but this is the closest to the Strip.
