This is a nice little two-bedroom apartment (not really “spacious,” though) located on the border between Arrondisement 13 and the Latin Quarter, about equidistant between the Gare d’Austerlitz and Place d’Italie. So there is easy access to the metro system through various nearby stations. Walking to the Seine is about a 15-minute stroll.
The apartment is modestly/economically furnished with queen beds in each bedroom and modern double-pane windows throughout, which keeps it quiet throughout the day. The third main room is a combined living room (three-person sectional sofa), simple dining table with four chairs and a facility in one corner with small refrigerator, sink, hobs, oven and dishwasher. There is also a small bathroom with an excellent shower and plenty of hot water (and a small washer/drier for small loads of laundry).
Local sites worth seeing are the Jardin des Plantes (wonderful gardens with a zoo), Rue Mouffetard (for foodies), the Pantheon (for historical figures) – all within easy walking distance. Even Notre Dame is only about a 30-minute walk away, much of which can be along the quiet riverside quais rather than the busy streets above. (The Bombardier is a good bar/restaurant to watch European football with an English-speaking staff.)
Overall, this apartment would be a bit small for four adults, but we were only three and didn’t spend a lot of time in the apartment. A family of four with two children would also be comfortable here. The on-site person who looks after the apartment (I never met the owner) speaks only French but was very friendly and accommodating.
However, two days before we were scheduled to arrive he asked me to cancel my Airbnb reservation and give him cash upon arrival instead at a rate below what I was paying through Airbnb. Yes, I would have saved a few hundred dollars, but Airbnb would have been robbed of its fee. And who would trust a total stranger in a foreign country to honor such an agreement? I said “Thanks, but no.” I don’t know whether my refusal on this point was the reason, but after we left this owner made dubious claims we had caused $700 worth of damage to the apartment’s furnishings and bedding. I’ll have to work through that over the next couple of days. I’ve never had any Airbnb owner make such a claim, so I am not sure how this works. But I recommend any rental of this property start with a walk-through of the property with the owner and an inventory of the property’s contents. And a walk-through also on the final day of your rental.
