Alain's place is just as it looks: charming and stylish and perfectly located. If you want to stay in a very clean, central apartment in a lively neighborhood with a lot of modern touches and traditional charms, it is perfect. For me, it was an easy place to work and a great base for exploring Paris. Its worth noting that there is a bit of street noise (as always in the Marais -- it's hopping); it's people and city noise (and in the living room and upper bedroom only), not traffic noice but worth a cheap pair of earplugs if you are sensitive. For buildings of that era, there is amost no noise from neighbors or the courtyard and it is was toasty warm in the winter (with new heaters and plenty of hot water) -- a rare treat in the older buildings in the center of town.
Alain made check-in and check out and everything else very easy.
