The location is great! Some might think the neighborhood is too quiet in the evenings (not many bars and restaurants with 5 min walk), but I thought it was pretty, clean and safe and you can hop on the metro easily to get to busier areas in Paris. If you walk 15 min your are in the 17th, which is a livelier neighborhood at night.
Erwann is very friendly, helpful and super quick with responding. I would definitely recommend staying here when you are planning a short trip to Paris. Great value for money!
