I had a great stay at Sonia's apartment! Although I never had the pleasure of meeting her, she kept in good contact with me and was very helpful. The neighborhood is great for someone looking to really delve into Paris. I am a 22 year old recent college graduate and I met many people my age and found lots of fun places to hang out. Canal St. Martin is a short walk and there are two major parks very close by. Buttes-Chaumont is a great place for a picnic or a drink at Rosa Bonheur. The apartment was cozy but had plenty of space and lots of light. Those 6 flights of stairs are long but well worth it once you reach the top of the building for great views.
