I always hate encountering such Gerlish hybrids.
My advice:
1) Keep English grammar & common sense firmly in mind and write only "hotel" -- you can build in the adjectives "comfortable" or "luxury" or whatever your context calls for somewhere,
or 2) Ask the client to specify what they mean by that non-word: i.e. luxury, high-quality, etc..... If they don't offer a proper answer, see #1.

IMO, it's not my job to incorporate a German author's false assumptions about what the Engl. language will tolerate.

I was not intending to claim that Komfort is English, Nicole, and your extremely inappropriate and disturbingly unprofessional email sent to my personal account has been deleted. Ende der Geschichte.

Working as a translator in Austria for two decades now, I've lost track of how often I've seen "Komforthotel" used, and when I'd ask the client about it, they most often said they meant the obvious – their hotel is "schön, komfortable, ruhig". (Not a one using 'Komforthotel' ever "admitted" they ran a luxury hotel, strangely enough.)

Anyway, I often ended up doing some research about the hotel itself and incorporated that description, to help it sell itself, thus avoiding slavishly translating the term 'Komforthotel' literally.

I see David and Chris's suggestions tend toward this solution too, and I agree with their versions. Your context/client will tell you for sure.

Continuing good luck in parsing this favourite (Austrian-tourism) Gerlishism, Courtney!
