This was our second stay at Cosy 3. The location is superb! The apartment immaculate. You will immerse yourself in the culture staying here! Keep in mind this is a historic build so while the building and amenities have been upgraded, the stairs are what they are for size. I normally would not comment but it appears some see this is a distraction. It's not, this is Paris with a ton of history and beautiful ancient architecture. It's all part of the experience. You cannot beat the location or the apartment layout. Grocery store if 4 minutes away (Franprix) door to door. Open air market on Rue Mouffetard is 8 minute walk. You will have everything you need fresh, open daily 8-1pm. You share a laundry room. We had no issues and we stayed 10 days. The drapes are light and sound proof. Because of the cafe culture the bistro's leading up to the weekend will be busy and a lot of fun (Le Petit Cafe is amazing!). We look forward as a family staying here again.
