My family (husband and 6 year old twins) and I stayed for a month at Gaia’s wonderful Marais apartment.
I’ll start with the location-wow, just wow. The Marais itself is perfectly located to access anywhere in Paris quickly, and the apartment’s location within the Marais is just as perfect. Everything you could possibly need (grocery, market, boulangeries, meet and cheese shops, wine, cafes, top rated restaurant and bars, boutiques, etc) is located within a 1-5 minute radius. Public transportation is also very easily accessible with multiple metro stops nearby.
As for the apartment, it had everything we needed for our family of four for our month stay - we only had to purchase some basics: dishwashing detergent, laundry detergent, shampoo and halfway through our stay some trash bags. There is a washer (no dryer - just a drying rack) within the unit. The two upstairs bedrooms are simple but light and airy. Note to parents of young children: the spiral stairs have no railing on the lower half. We had to have a serious talk with our six years old about being careful on them upon arrival but had no issues whatsoever. The kitchen and living room we found to be very large compared to our other stays in Paris. The kitchen is fully equipped and the living room, though sparse, had just enough to make it a comfortable spot to rest between exploring the city and before bed. The most wonderful part of the apartment is the beautiful courtyard, which is accessed from the living room and can be gazed upon from that room and the master bedroom. Lastly, we were there during a heat wave (several days in the 90s F), and the apartment stayed relatively cool until the 5th day of extreme heat. We did buy fans and it really wasn’t all that bad, even on the worst day. We had friends in Montmartre who’s apartment was so hot they left town, and we never contemplated that.
The host, Gaia, and his associate, Noel, were extremely responsive and helpful before and during our stay. Check in was very easy. They have created a house manual with everything you need to know about the apartment and also with many great recommendations for things to do in and outside the neighborhood. Check out was a breeze.
We loved having this place as home base and hope to be back very soon. I highly recommend it!
