Quick response (communication): even though Lily and her brother weren't there, they coordinated with us a couple days before hand. We were able to check in early since our fight came in early, even though usual check in isn't until later.
Conveniently located to the metro, RER, and the Eiffel Tower. Walking distance from multiple grocery stores and restaurants.
Everything was as expected per the air bnb website.
The apartment is small but snug and cozy. The tub is huge which makes the bathroom seem tiny. The washer/dryer is also in the bathroom. Hence, tiny bathroom. Kitchen is also small, but has the necessities: dishes, cups, glasses, bowls, silverware. Small oven for heating up food and small fridge for chilling your wine or food.
One thing to note is the spotty wifi. For an apartment that sleeps 3-4, 3-4 devices should be allowed to use the wifi. In this da and age, everyone has a smart phone or a laptop/tablet that would gratefully use wifi. Also, the TV has weak signal (or some other problem), rendering it unwatchable. But that's alright, we didn't come to Paris to watch television!
Overall a great option for location and convenience!
