Alexis' place is very convenient to the city centre (20 mins by train) and just 15 minutes walk to Montmartre. Very easy to check in and checkout with all the details given prior. I would also like to point out how accomodating and helpful Alexis was to add an extra night for us since we had to reschedule our flight. It was a very great accomodation overall and would love to be back when we visit Paris again!
