We were 2 families travelling together who wanted to have separate yet close accommodations and François place was perfect for this. Basic, but very comfortable beds and great water pressure in the shower. Sue, who met us on arrival, was very friendly and helpful with local knowledge (especially the tip to take the no 30 bus to Trocadero for the Arc de Triumphe/Eiffel Tower). You are in a block of flats with all the accompanying neighbourly noise, but this seemed somehow less disturbing in French (being English speaking) and added to our experience.
Montmartre is a great area for shops, bars, restaurants and you've both the Sacre Coeur and the Moulin Rouge within very short walks as well as easy access to public transport. There is an amazing gelato place called Amorino on the Rue des Abbesses that make your cones into flower shaped masterpieces - a definite must!
We had a lovely few days in Paris and would definitely use François place again should we return!
