Executive summary from two nights' stay in November, 2012: good location for exploring Richmond; parlour suite was comfortable, spacious, and decent value for money; staff was helpful and pleasant; continental breakfast was just OK.
Details: I liked the Linden Inn's arrangement of connected, old row houses surrounding an interior court yard. The parlour suite (an upgrade -- thanks!) was clean, enormous, comfortable, and well-furnished -- but (grumble, grumble) I thought the ginormous room also should have included a small-sized frig (without paying extra for it) and a few plates, glasses, and cutlery.
Biggest area for improvement: the included breakfast was very basic for the hotel's mid-$100s tariff. Its range of offerings (awful burned coffee, basic breads, yogurt, generic waffles) fell well short of what you'd expect to find in any modern traveler's hotel (e.g. Marriott Residence Inn). To cite a specific example (and without meaning to be petty): the kitchen staff declared that the oatmeal was "all gone, got to get there sooner" 45 minutes before the end of breakfast. Cheapo -- what's that about?
Minor gripes aside, I would recommend Linden Row Inn (and especially in the spring and fall) to others wanting to experience an idiosyncratic old-times atmosphere located in the middle of an interesting city.
