I m surprised that only one guest mentioned here the very uphill walking to the 7th floor -6th floor in Paris as they don't count the 1st until the 2nd floor. It is very hard to carry a heavy suitcase all the way up to the 7th and not make any noise in the stairway as there were lots of instructions to not make any noise. It's a very old building, with a narrow stiff wooden stairway, and noisy old floors. There is no AC or even a fan in the apartment, during the summer months could get unbearably hot in the tiny bedroom as it was when I was there. I m not sure how some guests leave a review not mentioning the climbing of the stairs, or even mentioning that is good for 4 people when barely fits one in the bedroom. The bathroom is super tiny that there is not even space to put your toothbrush -literally speaking. The neighborhood is very charming of course, it's the old artistic Montmartre, but public transportation to get to the other locations in the city is a bit complicated as one needs to change trains and take a bus then walk uphill. Even though it's advertised as 100 Euros per night, in the end the bill comes to more than 200+ per night.
