We booked to stay at Sébastien and & Marion's place last minute during the heatwave in France. They were so accommodating and really communicative before we arrived at the apartment to make sure we got in okay. Their place is beautiful and is really spacious - especially for Paris! There are lots of stairs to get into the apartment but the location is perfect and within walking distance to the Seine and on the doorstep of Le Marais. I would definitely book again for my next trip to Paris.
