Temple Square is where I’d like to live in Paris ...if I could, and Renou’s apt is located right there. Stayed for 2 nights/3 days, was always quiet inside, lots of light and spacious. Good quality restaurants frequented by locals right next to you, rue de Bretagne feet away and the whole Marais neighborhood. Subway 3 minutes away at place republique can get you everywhere quickly.
If you wanna mingle with trendy locals and feel the local vibe, this is the place. Maybe not the most affordable or luxurious but you pay for location after all.
Also ...you have to know it’s 5 floors up the stairs. So not for everyone...
Would very likely book again.
