Smooth check in process--Building and parking security are excellent and easy to use with cell code access. Literally the *only* downside is not the owner's fault; St. Louis this year approved recreational marijuana use, and all the hallways, lobby, elevators, stairs etc. reek horribly of marijuana smoke. The apartment itself uses a lot of air fresheners (while better than the public spaces odor, is a bit over powering). It is VERY clean and very hip (although not much privacy between bedrooms as the walls do not go all the way to the ceiling). Would definitely stay again-- close to all the fun tourist-y things to do (Arch, Union Station, ballpark, etc.).
