Yankel's apartment was conveniently located near all the bars and restaurants you'll need. We used L'Open tour bus and the was a stop only about 6 mins away (walking). A few qualms: water damage on the wall outside the bathroom where the shower is. Gives the appearance of poor maintenance. Smell coming from pipes. Quite possibly a European thing with the sewage but it was not pleasant.
We got to meet Yankel. He was nice. Very helpful and forthcoming with pertinent information.
Apartment is definitely cozy (read: tight) but fits the bill for providing a comfortable sleep (a rather tight) shower and quite the workout going up and down the 7 flights of steps to get to the unit as there is no lift. I would recommend this space but would probably not return as the 7 flight trek with a 50 lb suitcase is not my idea of fun. Nevertheless, this apartment was a great way to get a taste of living like a Parisian which is why I love the airbnb concept...you can live like the locals.
