Sylvie's apartment in Le Marais area of Paris is so special! My husband and I stayed for 8 days and were entirely comfortable and accommodated in our visit. The check in is super easy with a code provided to gain access to the building, and even though Aicha the manager doesn't speak English and we speak very little, French, we all understood one another perfectly. Sylvie's communication was always quick and timely and extremely helpful.
The apartment is sparkling clean and beautifully--and comfortably furnished. It's a very large space, much larger than it appears in the photos. The kitchen is well stocked, so you can cook in if you like (but why would you want to?) and the bonus for us was the washing machine in the apartment. This allowed us to pack lightly. Sylvie very generously provides soaps, shampoos, and other bathroom necessities for guests. The location in the Marais provides any type of store, restaurant, and market you desire within steps of the apartment, many of them owned locally and selling their own wares. There are two Brasserie restaurants just below the apartment, we recommend Le Bouquet des Archives for coffee. There's an outdoor market open 6 days a week called Marche des Enfant Rouges where we found local cheeses, wines, and fruit. We wanted to see museums and cultural sites, and pretty much walked to everything using Sylvie's place as our home base. Long story short: pack light and buy what you need in the neighborhood.
Le Marais is known as one of the trendy spots in Paris, and it's lively! But when you are ready to rest, the windows are very sound proof and the dark curtains allow for good sleep..
