This is a fantastic place. We really enjoyed our stay. Location cannot be beat for those who love the Marais (for us, this is the best area of Paris).
Numerous outstanding restaurants a few steps away (try Dessance on Rue Des Archives - wow), as well as cafés and bars. A few metro stations are about 5-6 minutes walk.
The apartment feels very fresh - all new and decorated with fine taste that manages to retain coziness and a homey feel. Really nice kitchen amenities as well as a very comfortable bed. The shower is very spacious - we found it surprisingly enjoyable. The apartment is rear hence it is very quiet, day and night. Highly recommended!
