The space is as shown--very functional even though small: the bed (suitable for one person) is quite comfortable with a good comforter provided for the season; the shower is a very good size and modern with plenty of hot water; sufficient closet space for a relatively short stay; a good-size small refrigerator for water, prepared foods, cheeses, etc.; two burners (not used); and a good sink.
The "studio" was very clean as was the bathroom down the hall.
The "living area" under the bed is very small and requires stooping, so, in that respect, expect functionality over comfort except for the bed.
The apartment is in a very chic area near the Four Seasons George V and very near Metro George V which allows you great access to all connecting metro lines (at least those I required). There is a Monoprix store nearby on the Champs-Elysee, both retail, including toiletries, etc., and a food store with a separate entrance at the back for prepared and other food items, wine, and liquor at reasonable prices.
Although there was some lag time in responding to inquiries, everything was satisfactorily addressed (I believe I was there during a school holiday which caused the delay).
I would definitely return.
