I go to Quebec frequently, and generally avoid the higher priced hotels in favor of a less pricey and more personal experience. Au Manoir St Genevieve has a great location on a quiet street a block away from Terrace Duffferin and the Chateau - couldn't be better. It's a fine old house, possibly once serving as lodging for military officers in days gone by given the proximity to the citadel.
We booked two rooms and found both clean and comfortable - I would recommend asking for rooms off the ground floor since rooms on upper floors are brighter, prettier, and seem to have nicer architectural details. (I don't think there is an elevator though.) Our two double rooms were $100 Canadian each (or about $80) - not too bad for the height of the season - and we had a parking voucher for $11 Canadian per day - parking was about 2 blocks away at City Hall.
Both rooms were spacious and had TV and AC. In both rooms, sinks/vanities were in the main room, and separate bathrooms with tub/shower & toilet were small but adequate. My room on the 2nd floor had beautiful moldings, lovely windows, and was quite attractive.
The proprietress and staff were helpful and pleasant. Coffee, OJ and a lackluster croissant were available in the morning, but we preferred to breakfast at the wonderful Conchon Dengue in Lower Town.
This may not be the place for people who are accustomed to luxury digs or who prefer full-service hotels and cookie cutter comforts. This is comparable to many of the European small hotels that are often long on price/value, cleanliness, and character, but that don't offer the predictable amenities that add to price. I enjoyed it as did my friends and we wouldn't hesitate to stay here again or recommend it to others.
