My two sisters, baby and I enjoyed our stay here. The flat is lovely, is as described, well situated (right next to the Sacre Coeur and two stops away from Gare du Nord) clean, warm and brightly lit. It is a secure PIN-coded site and the flat is on the 4th floor which you can access by the stairs or the elevator. Though small, it can comfortably accommodate 3-4 adults (no more) with small cupboards for storage. The main bed is comfier than the sofabed, although this was large and folds away without a fuss. The kitchenette is well equipped and the bathroom is spacious with hot water and a radiator. Jacques left us a bottle of wine which was a sweet gesture! We stayed here for a week and cooked in on some evenings. If youre looking for decent brekkie, theres a Pret just round the corner (right next to Lindt!). We were within walking distance to most sites we wanted to visit so the location was ideal. There are two train stations close by - Anvers & Pigalle which connect well to the main arteries of the Parisian Metro system. Jacques was able to answer most of our questions via airbnb messaging and was helpful. His lovely friend Linda greeted us and she was very thorough in her introductions.
Overall, we had a good stay and will be returning when back in Paris again. :)
