Spent a week at D's, had a business meeting at a mccormick place ($10 uber ride or 20min walk) ; the room is nice, clean, and very comfortable ; the living room is spacious and a very clean and modern kitchen, as is the bathroom.
The neighborhood is pretty quiet and residential (importantly, the place is near the train lines, so sometimes you will hear bells and trains, nothing to worry about). There is a nearby grocery and dry cleaner and whatever else I need.
I found my experience pretty good and was worth the value.
I am very grateful to D, that was a great host and such a nice girl.
