Charlotte's space is exactly as described. I stayed for a business trip and she kindly let me use the living room for conference calls and was very amenable to my full schedule and adapted check in/out.
The room is small but comfortable and the bathroom seems to have been recently re-done. Bed is comfortable, more than the standard amenities are provided, and wifi works well in the room as well.
Moreover, Charlotte is a delight! She was not only helpful with the usual AirBNB stuff but greeted me with coffee, cookies, and brownies. She'd set out a folder of London activities/restaurants/essentials (which sadly I didn't have time to use). She was also extremely helpful when I needed to have a last minute amazon delivery do to a phone mishap.
Would highly recommend!
