I don't really think using the adjective "still" really works in English to instill the idea of quiet/calm... Makes me think that the hotel itself is still - unexciting and dull.
That being said, it is still a brandable domain for a hotel. The way it is worded it would need to be the site for a specific hotel, not a generic site about still hotels. So understanding that, you would need to find an enduser that wanted to name their hotel that too (if they didn't) already... personally I think it is a tough sell. I'd put it at regfee/$0 for reseller (too difficult to sell with high risk) and low $xx to low $xxx for enduser, assuming you can find one. If you do find an enduser, it is more likely to be a smaller business and they pay much less.
Hope this helps!
