The view from Martine's apartment is unbeatable, you have a different view of the city from each of the large windows and balcony that span the entire length of the apartment. The location is steps from the foot of the Sacre Coeur in the cute neighborhood of Montmartre and there are a ton of delicious restaurants nearby and a grocery store on the block which was super convenient. The Anvers and Barbes-Rochechouart metro stations were only a couple blocks away and easy to walk to for transportation to the rest of the city and the RER. The heating in the apartment also worked really well which was important since we visited in January when it was really cold. Martine has a couple of umbrellas hanging in the apartment which are helpful for rainy days. The apartment was clean and looks exactly like it does in the pictures and Martine was very sweet and welcoming during check-in.
For dining nearby, I'd recommend the lamb chops at Le Cave Gourmande, which came with the best baby potatoes I've ever had and really delicious string beans (worth the extra wait time for them to prepare this dish, just order some starters--everything else we ate there was equally amazing), creperie broceliande for really nice buckwheat crepes which are crisper than the ones we're used to in the states, and les Arlots if you want to dine at one of the hot spots for locals-- just make sure to make a reservation in advance or you can try to get lucky like we did and go around 7:15 on a weeknight and ask if they have any available tables or cancellations. The first seating was at 8pm and we just had to make we were finished by 9:30 for the next reservation. The octopus ceviche here was one of the most creative and memorable dishes of our trip.
I also recommend picking up a baguette from le grenier a pain (boulangerie) and some charcuterie and cheeses from any nearby charcuterie/fromagerie and grabbing some vin chaud (mulled wine) from one the of the vendors near the sacre coeur and taking them to the top of the steps for a mini picnic with an unrivaled view of Paris.
Thanks for the great stay Martine!
