This apartment in the 2nd arrondissement in Paris was perfect for our needs. The location was great - close to multiple metro stations (we traveled by metro extensively) like the Bourse, Richelieu Drouot and Opera stations, and only a 15-20 minute walk to the Louvre. It is also a 2-3 minute walk to a small local grocery store around the corner which was very convenient.
The apartment has a washer/dryer that we took advantage of during our relatively long stay (10 days), heating and air-conditioning (although we were there in October, and didn't really need heating and simply opened a window for cooling at times), and a small refrigerator.
The apartment was clean, check-in and check out were a breeze, and the hosts were great about communications and orienting us to the apartment soon after our arrival.
This apartment was also quiet! We slept great after long days of sightseeing. There was no street noise, and we heard very little activity from neighbors. The only disadvantage to this location is that it is on the third floor and (as with many Paris apartments) there is no elevator access. The three flights of stairs could be challenging if you have mobility issues.
We loved our stay in Paris and this apartment made our trip easier and more enjoyable.
