I would not put it at auction. Like the previous appraiser said, Geo domains are normally outbound domains, which means quite some work. Decent Geo names go for $10 - $20 here on NP.
I would do outbound. I don't think it is a good geo domain, its decent. The problem for me is that it is plural. This means you should target hostel chains in the US or price compare / booking sites.
Also, for hostel, more specific is better. For instance: I see a name like HoustonHostel sell much faster than UnitedStatesHostel, even though there are less hostels in Houston.
Just my 2 cents.
