I will be coming to Denver in a couple of weeks and I'm looking for a nice hotel in a good area of downtown Denver. I have never been before so I would like some insight before I make any reservations. I am trying to keep the hotel within a resonable driving distance to the international airport and the botanical gardens (so nothing too far from either location). I have seen good deals directly downtown and in the Tech Center. Any suggestions are appreciated. I am mainly concerned about finding a safe location with a clean hotel in the $100-$150/night range.
