This is an excellent location to explore Paris. It is on the RER line to the airport, so very convenient. Also a large grocery store just a few blocks away, as well as several small ones even closer. Restaurants and boulangeries are right outside the door. Easy walk to the Louvre, and Le Marais neighborhood.
Apartment itself was great. Very convenient to have small kitchen for breakfast and snacks. Bed was comfortable and full size shower with excellent water pressure was a plus. We enjoyed having the extra space (we were 2 people).
Just a note: it is on the 4th floor and there are a lot of stairs. Worked out fine for us, but could be a concern for some.
Hosts were on top of their game and very easy to communicate with. Would definitely stay here again (and probably will!)
