Ombeline's place is in a great location, the is reminiscent of the East Village or parts of Brooklyn. If you want to be in a hip part of Paris away from tourists, and don't mind some of the evening noise you get as a result of being in that type of environment, this place is for you. You'll have plenty of options for local cafes, bars, and restaurants. Speaking a little bit of french is helpful in a neighborhood like this, to at least be polite with the effort.
The location is easily accessible by Metro. The apartment is walking distance to attractions like the Pere Lechaise Cemetery, shopping in the Marais district, the Canal St. Martin, and a slightly longer walk to the Ile de la Cite.
The apartment itself is pretty cozy. In our down time we enjoyed listening to Ombeline's vinyl collection which includes just about every Sufjan Steven's record, the Talking Heads, Velvet Underground and much more. In unit washer for laundry is a big plus! Do note that the bed is in a lofted area above the living room, so if you have any mobility concerns that may be a challenge for you to get up the steps or manage with the low ceiling.
Ombeline was a great host. She was very communicative over email and flexible with our arrival and departure times.
Overall I had a wonderful experience. Next time I'm in Paris I'll be checking to see if this unit is available again.
