There are several amazing things about this listing!
First, the location is GREAT. If you chose to, you could take a 20-30 min walk to just about every major sight in Paris. Also, the metro station is just a 1-2 min walk directly to the left when you walk out of the apartment. From there you can get just about anywhere in the city.
There are tons of great restaurants and a few grocery stores in the area.
The apartment is equipped with everything you could need for a short or extended stay in Paris. We were in Europe for a month and were able to use the washing machine to do some laundry!
The apartment itself was more than enough space for two people and I think the couch folds out so I'd say three people could stay there comfortably.
We didn't meet Jacky; Victor actually met us to let us into the apartment. Victor was very nice, showed us how things worked and even answered a quick question I texted him one day about navigating the city. However, Jacky was extremely communicative and checked on us everyday.
The wifi was FAST. Shower big and lovely, and the kitchen was functional. The only con was that there was no AC. We visited in July so it was pretty warm but it cooled off nicely at night with the windows open and we slept just fine.
We would definitely stay there again if we return to Paris.
