Had a lovely one night stay in Les Piaules!
My receptionist was super cool - had lived in Australia and seemed to speak at least English, French, Spanish, and Portuguese! All of his instructions were clear, meaning I found my room and bed easily, and fell back on his recommendations if I needed something to do. e.g. the rooftop had an awesome view of Paris, particularly Sacré Cœur and the Eiffel Tower!
On Thursday nights, they have a jazz band in the bar on the ground floor. Coupled with my free welcome drink, it was a great spot to get chatting with locals or other people from the hostel. They also have a DJ on Friday nights and a free walking tour every (?) day.
In terms of the room, it was tidy and comfortable. Every bed had a curtain for privacy, a light and power point, and a locker big enough for my large hiking pack and day pack. As a tall person (195cm), I was impressed that the bed was not only super comfy, but also long enough for me!
Would definitely come back :))
