It doesn’t get more convenient than Sébastien’s place, from which you literally can see the Stravinsky Fountain. You are walking distance of many attractions, restaurants, bakeries, small grocery stores, pharmacies, and other places of interest. You can also hop on the metro walking less than 10 minutes, which allows you to connect to other lines and get mostly anywhere in the French capital.
I was shocked by how spacious the studio was. It worked great for my husband, our kiddo, and me as our home base while we explored Paris. Our kid who has always slept with us during vacation actually claimed the small bed for himself and slept in it happily each night.
One piece of advice to avoid the scorn of a taxi driver: don’t get dropped off and picked up right at the address. Rue Saint-Martin is not really great for vehicular traffic and we saw a lady get ripped apart by a cab driver when he arrived to pick her and her party up. It was embarrassing and I’m sure it was awkward during the ride. Use 15 Rue du Renard, which is just about 1.5 block from Sébastien’s place. We actually just waited there for a taxi without calling for one and there were four that started driving in our direction within minutes.
