Nicolas is a very gracious host, the airbnb room is lovely, and the apartment is extremely close to Gare du Nord and Gare de l'Est- I highly recommend this listing!
I arrived in Paris on a Tuesday but wasn't scheduled to stay with Nicolas until Wednesday. Nicolas let me drop my luggage on Tuesday afternoon and kindly stayed home for an extra hour when I got lost on my way. His communication before and during my stay was very clear (my French is terrible, so he communicated with me in English). Again, I highly recommend this listing!
