I'd give this 3 and 1/2 stars. The location is excellent whether you are a 1st-time visitor or black-belt Paris traveler. Bonus: the street, rue Mandar, though so very well situated, was surprisingly quiet at night. Building and check-in definitely as others describe - rather meh and getting keys more cumbersome than most but, hey, it is the city and we appreciated self-check-in (and 2 sets of keys). The unit itself, once inside, is as represented -- a small, updated space with newer outfittings, if basic. Not even a coffee pod offered but plenty of Franprix, Monoprix, etc. around. Bathroom is bright, new, and better than most. Building has a lift for luggage and unit is convenient one short flight up otherwise. Like many Paris apartments, there is street lighting right outside the windows that might bother you - bring a sleep mask if so. There is also a little curtain that helps. We decided if you're young students, budget travelers, or an unfussy type this is a perfectly fine (and even nice) place especially given location. If you're a more discerning traveler this will not be your best bet. For the $ and our purposes on this visit (and given our experience living in Paris and knowing it's all a trade-off) this was fine/decent not amazing. Host communication okay - not fast or warm but did the trick. Note re airport transport - couldn't be easier on RER from Les Halles/Chatelet. G7 or uber a few steps down off rue Montmartre also easy.
