Instead of attacking the first person that tried to answer your unfocused questions, why not provide some details about what you actually want to know.
First, although I've never been to the Renaissance Vendome, it only took me 30 seconds to find it online and look at some pictures. That gave me a good understanding of what USirritated was saying.
Second, the only people that can answer your second question are MDtR-Chicago and his/her wife. A private message is the only way to get that answer.
Back to specifics: As indicated above by everyone (including yourself), the term "hip" does not have a universal meaning. It will vary greatly based on location and demographic. If you want legitimate suggestions, why not list the city of travel and a few sentences describing the atmosphere you want at your hotel?
