I definitely consider myself budget. I offer a full apartment, but it's up a flight of wooden steps, the floors need an update, and the kitchen and bathroom haven't had more than basic updates in 40 years. But I stayed in a lovely cottage this weekend that inspired me with ideas to make it look updated without spending more than $50 or so.
But I keep it very clean, have new mattresses, and provide a stocked pantry with basic snacks and breakfast. But then I also have used furniture, basic linens and towels, and it's above a garage. So my base price is equal to the local motel (usually $70/night) for 2, and I'll take up to 4 at $10/additional person. I have a $25 cleaning fee. I'm saving up to redo the bathroom, then the floors, then enclosing the entry way and updating the stairs so not as steep (this is my 2-3 year plan). Hoping to move up to high-end budget instead of lower due to things I just can't afford to fix right now.
