As other reviews have said, the morning light in this flat can't be beat and it is a sanctuary in a hive of activity. The neighborhood has a lot of restaurants, good bakeries, great markets. I recommend Pâtisserie Tholoniat, Afendi Paris, Le Pain des Copains, PNY Burger and for old-timey Paris charm there is Brasserie Floderer behind the flat. Though I tried to patronise the markets, I confess it was also very nice to have FranPrix steps away.
On the near corner there is a reliable brasserie called Le Napolean and perhaps most important for those of you planning to drink and party or in need of a reliable cheap lunch, at the corner I give my hats off to the guys at Munich Kebab. It's also open late. Very friendly too and I loved them!
The whole neighborhood is open a little late -- which I liked but would lead me to the few critical points. At 43 I felt a little old for the trendy hip surroundings, though I did appreciate. That's not a knock on the flat of course, just information for your decision making.
As for the flat, I do recommend it. On the basics. WiFi worked great. There are enough kitchen dishes. Water was always hot etc. Washer worked great. I suspect this would be a very hot flat in the summer, but in September and October is was just about perfect and the heat worked well when needed. All good here.
My critical points here. I'm a big (or some might say overweight) 6'2" American guy and the the furniture wasn't terribly comfortable for me for a long term stay. If you are on a short basis that doesn't matter. For me it was a clean flat but the shower may be a degree below what my sister would accept.
Finally, hats off the host who was very communicative. I needed replacement sneakers and my size (US 13 / Francais 47) are tough to find in Paris. He provided advice on ordering online and received the package. for me This was my only sticky wicket in the stay and he rose to the occasion and I suspect would have been there for more if needed. Though we only met briefly, his flat I think matches his personality and you will feel like you are in a home and not a bland Airbnb.
