This is really a charming place! Sebastien, my host, and the building gardienne, Claudia were both fantastic. They made my arrival as anxiety-free as possible; I felt 'chez moi' very quickly. The location was perfect for my purposes (research and revisiting certain neighborhoods). The studio is small (as advertised, it's a former chambre de bonne), but it has everything the traveler needs to be comfy-- a great bed, wonderful natural light (and it's well-lit at night), a haunting view, and it's quiet. There's also a fine shower, and more-than-adequate kitchen provisions. The place is very clean and has a good supply of bed-linen, towels etc. Sebastien made time in his busy schedule to pop in & see me --much appreciated-- and Claudia was continuously available: to change a lamp-bulb, to help me with some mobile phone difficulties, to offer post-checkout security for my baggage on the last day. I would say that she really looked after me wonderfully. The toilet is a shared one (again, as advertised) in the corridor outside, but this is absolutely not a problem as it's just next door. In fact, the whole upper story of the building is extremely quiet and seems hardly used.
