We loved the apartment! And even after reading the Airbnb reviews and description, we were blown away by the incredible view. We could have gazed out the window for hours watching the Seine, riverboats, and pedestrians - tourists, locals walking their dogs, kids heading off to school each morning - and all the people just hanging out by the banks at all hours.
The location is just as incredible - on the Ile St. Louis and close to Notre Dame, the left bank, metro stops, great inexpensive restaurants, nightlife, and the Marais district. We highly recommend the restaurant next door, L'Auberge des Deux Ponts. The owner is very nice and does about everything there, as far as we could tell. Great food and great value. Get there before 9pm because it's small and starts filling up around then. And leave time for a leisurely meal and great dining experience.
Should also mention that Ile St. Louis is the island of ice cream. Every other person there is walking around with a cone or dish, thanks to several Berthillot locations and our favorite, Amorino.
The apartment is as described, one room with a comfortable fold-out bed, kitchen, bathroom, and a washing machine that also dries the clothes. Everything we needed and more. There is street noise and some partying by the river in the wee hours, or as the French say, the oui hours, but all expected from the reviews. Rather than keeping us up, the sounds of Paris at night lulled us to sleep.
Many thanks to Boris and his assistant Nawal for all their hospitality!
