A lot of people here have commented that typically Airbnb listings are cheaper than hotels, especially if you offer the kinds of space or amenities that only higher level hotels provide.
Just for grins (or maybe important market research) I looked on Google maps to see where the hotels are located near me and how they are priced. My location is in outer suburbia in between two major freeways but not really close to either. There are clusters of hotels near some large business areas, but all of them are on the freeways. All are 1-2 star hotels, mostly budget chains, and priced between $79-120 a night (current pricing, this might change with the seasons).
I did a search for 3-, 4-, and 5-star hotels in Houston and they are grouped in the downtown and Galleria areas mostly, with just a few on the west side near a business area. Those prices quickly jump to the $100 - $350 / night range.
My price is $46/weekdays and $51/weekends. There are extra costs like the $10/second person and the $15 cleaning fee, but still the total bill will be much less. I have kept a close eye on the other Airbnb properties in my area and the serious long-term people are charging about the same, or even less.
So I would definitely say that Airbnb listings here are a good deal, using single room in a house as a comparison (rather than whole house, which offers kitchens and living rooms which hotels do not).
Do other posters charge less than local hotels or is it about the same?
