Pros: Absolutely incredible views of the city including Eifel Tower. It is hard to resist looking out the window as the day goes by. Perfectly situated at the heart of Montmartre and from shopping. Clean and well equipped. We all slept very well there. We did not get to meet Paul personally, but his instructions, logistics and scheduling were excellent.
Cons: This place is not ideal when carrying a lot of luggage, or for people who are not fit. You will need to climb 5 stories without an elevator.
