We really enjoyed our stay at Nils’ apartment - it was well arranged with a nice kitchen and eating area, double bed downstairs and another up in the mezzanine/loft as well as an extra bed downstairs which doubled as a couch. It felt homely with his books and cds and he’d thoughtfully left some basics for cooking. WiFi worked well.
The 11th is a v lively area with restaurants/cafes galore, supermarkets and bakeries close by and well served by buses and 10 mins walk to Bastille.
The place is at the top of several flights of narrow stairs so you need to be fit. There is no ‘living room’ as such although we didn’t mind as we were out in the evenings. Highly recommended.
