The apartment is centrally located, close to 4 metro lines and within walking distance to a number of famous sights within Paris. And yes those old stone walls are as beautiful as they look in the pictures :-)
The host, Arno speaks fluent French and English. Communication with him before and during our stay was excellent. He offered us lots of great tips on where to eat and drink in the locality. He is a real gentleman and one of the nicest hosts we have encountered via AirBnB.
I highly recommend this apartment for anyone looking to visit Paris.
