My wife and I have stayed at the Oxford twice on trips to Denver, and both times have been extremely impressed. It is an elegant, well-kept, "old time" hotel.
Rather than the electronic key cards that are used in most hotels these days, you will get a regular key that is attached to a large tassel -- you return this to the front desk each time you leave, which is a classic touch. (Their mascot is a little orange canary named Casey, who greets you from his cage right next to the front desk.)
Both times we've stayed at the Oxford were not especially busy times for the hotel, and they automatically upgraded us to one of the "Victorian Deluxe" rooms at no extra charge, and we didn't even have to ask. These rooms are quite big (350 sq ft. according to the website) and have large, luxurious beds and beautiful old wood furniture (wardrobe, dresser, desk, mirror, etc.) The only negative aspect to the rooms is the bathrooms, which are relatively small and still have what appear to be original fixtures. They were all very clean and in fine working condition; the bathroom is just somewhat unattractive and small compared to the rest of the room.
The Oxford provides several services that distinguish it from the competition. There is a luxury car service which will take you anywhere in downtown Denver (within a few miles of the hotel). They used to have a "classic" Cadillac, but this time it was a newer town car. In any case it was a great way to travel to dinner. They also provide overnight shoe-shine service.
The Oxford also has the coolest bar in Denver right off the lobby -- the Cruise Room. It's a pretty small place, but it has great Art Deco furnishings and a cool neon glow. You feel like you've been transported back to the 1930s, and they serve a mean martini. The location is nice -- right in LoDo (lower downtown) and near plenty of restaurants, Coors Field, etc.
Highly recommended -- especially for those looking for a romantic getaway or an otherwise classy place to stay in Denver.
