We had a perfect stay in Khal's apartment. It is in a fantastic location and totally quiet even though it's on Rue de Temple because it is in the rear of the building.
Everything is walkable for Le Marais bars, restaurants etc and the metro is literally at the doorstep for everything else. There's also a big Monoprix supermarket two door away.
The biggest plus for us though was that the apartment is a "real home" as opposed to a bland space fill of Ikea furniture 😊.
I woukd totally recommend Khal's apartment to anyone wanting to "feel like a local" for a patis stay..
