We stayed at Nathalie's apartment in June of 2017. The place is just as the photos depict. The apartment was spacious, modern and clean with a well equipped kitchen, dining table, small sofa, the chairs in the photos and a nice bed that had a partial wall to give separation from the main space. The shower was large, especially for European norms, with a wonderful rain shower head. There was also a wash machine which was a plus.
It is located across from a small park. There is no air conditioning so plan for that if it is hot. It was mid temp when we were there. With the windows and curtains closed during the day it would be a bit stuffy when we returned. But opening the windows and with the two fans that were there, it cooled down within minutes. Street traffic noise was minor at night...we slept with the windows open and with the fans running you didn't really notice any noise. At other places we've stayed in the Marais, street noise has been crazy even with windows closed. Not a problem at all at Nathalie's place.
The location was fantastic. Just a two minute walk to the metro line 3 and about 5 minute walk to the Republique station. Great cafes, wine shops, a fromagerie, Monoprix if you prefer, and other shops right out the door. Nathalie had stocked the fridge with all the basic essentials and left us a chilled bottle of Sancerre Rose (an easy way to our heart ;). Merci beaucoup Nathalie...we will certainly stay at your place when we get to visit Paris again (hopefully sometime sooner than later!). A bientot!
