My girlfriend and I found Jerome's place small but very functional, it has all the amenities, comfortable bed and sofa bed, shower with great water pressure and lots of hot water. It was nice to have the toilet in a separate space from the rest of the bathroom, especially in the morning when the other party is taking a shower.
We did not cook in the kitchen but did make coffee in the morning, using the coffee maker and keeping our milk and yogurt in the refrigerator.
The location cannot be beat, a block off Rue Daguerre with several bakeries, markets and eateries, a short walk to the Metro, best way to get around Paris besides walking. And a short walk from the RER station. RER train is an economical and comfortable 45 minute ride from CDG. The apartment does lack a bit of charm but we did not spend a lot of time there. We got back from a full day in Paris and crashed into our comfortable beds.
Most importantly, Jerome was a wonderful host and very helpful. He went to a lot of trouble making dinner reservations for us. He responded immediately to any questions we had.
Thank you, Jerome.
