I stayed in this apartment for several months as a student. Olivier made sure I had the necessities when I arrived and continued to help throughout with any difficulties I encountered. The space is small, yes, but not so different from most Parisian studios! I cannot emphasize how conveniently located it is - 10 min walk from Montmartre and Pigalle, ~7 min walk to Trinité, Saint Lazare, and Place de Clichy metro lines, ~2 min walk to Liège metro line. There’s a Franprix right down the street from the building and several cafes and boulangeries nearby! The area is quite safe, and very close to many cool cultural spaces in Paris. 10/10, recommend for any solo/couple travelers looking to stay in Paris, as long as you don’t mind the hike up the stairs :)
