Helene is a wonderful hostess. She was very accommodating, and the flat was in great shape. She even offered to pick us up from the airport! We had all we could need in the flat, and I believe this a truly airbnb experience (staying at someone's else house while they're on holiday).
The flat is huge for Paris standards, with four large bedrooms all of them with double beds. The hammock in one bedroom was my kids delight, they'd spend hours there reading all those Papyrus comics or their own books.
After about 40 days in the area, we didn't want to leave! The neighbourhood is very mixed, pretty quiet at night, and we loved the market right on our street every Thursday and Sunday. The location is great, and while it is not super centric (ie, the Louvre is not round the corner but a few stops away), we loved the park nearby, the canal, and all the atmosphere around. Our kids registered in some summer courses -for a week, we used the nearby swimming pool, there are all sort of facilities nearby and the tube is just round the corner. I highly recommend this flat, especially for families with kids. And should you have any doubts I'm sure Helene will make out for them!
