Great location on the North side of Paris, right next to Montmartre, just walking steps to it!
Next to the subway station and very near to the Moulin Rouge, with many food choices nearby and 100m/yd from a Carrefour supermarket!
Taking an electric scooter into the city it’s probably the easiest way to get downtown.
The only recommendation I gave to the host is to have more than just two (2) towels, especially when four people check in, and to have a couple of pillows and one blanket for the sofa bed - he’ll probably follow it.
Host with fast responses - if you check in after 8PM they’ll charge you extra €26!
