The district and location are good. Close to metro, with nice markets and bakeries nearby, Montmartre district is just in 15 min walks with great places for breakfasts and perfect evening time there. Flat itself is enough good for short (1-2 days) stay. We spent 5 days there and it was a bit difficult to be in such a small place. Flat is on the ground floor and hall is really noisy. Whoever comes home during night wakes you up as you can hear everything. There are no windows, the glass door on the photoes leads to the inner utility room, which doesn't open for aeration and so can't be opened during the night from the safety reasons. The bad squeaks and pillows are not good ones. But wifi works good, the host Guillaume was helpful with clear instructions and on time communication. Nice choice to explore Paris for a few days if you have no high requirements for a comfortable stay.
