This has come up under other topics, and I'm curious (and bored. Putting the baby to sleep... entertain me! ...
Do you consider yourself budget, and how do you define budget? (Is it based on what hotels offer/charge? Or what other Airbnbs in your neighborhood offer/charge? Or based on your personal sense of the word?)
I think our main listing is simple, perhaps even streamlined, but I would only consider it "budget" because it's half the price of the no-tell motel, our closest formal competition. (Full disclosure, our private room rents for about $70/ night, and during our season - mid March to mid November - we usually have 3-4 bookings a month between 2 and 5 nights. I'm very happy with that, so I think we are priced appropriately. For silly comparison's sake, the closest fancy hotel starts at $400/ night)
There are many Airbnbs in our area, and private rooms run from $45-120/ night.
We just (Thursday night! Whee!) added a second listing and I think this is very much a budget listing - it's a twin daybed on our unheated porch.
I know that sounds rough, but we've had people fight over an air mattress in our living room, so I think there is room in our market for this. (The air mattress was too much in our flight path. The porch actually has much more privacy even if it is still a shared room)
In my head, even though they get almost the same amenities as the private room (towels, shampoo, tea) it is budget because it's a shared room with no air conditioning. According to Airbnb we should be charging $31/ night to be in line with other listings, but I think that even at $45/50 we're still budget. (And there is a sofa listed at $300/ night, so I'm not the silliest listing in my area. I'm pretty sure that was just for a football event and they haven't bothered to de-list)
... anyway, comment away.
