Mixed bag, depending on your needs and preferences. We were here 3 weeks.
Pros:
- Location, location, location: Marie's place is in the heart of the Marais, and the Marais is, in our experience, the best place to be in Paris.
- Value: four people could stay here, though it'd be a bit cramped inc storage space. For the price, that's a definite value.
- Conveniences: the kitchen is very well supplied.
- Responsiveness: Marie is excellent.
- Quiet: despite being in the Marais, Marie's place is situated well back from the streets and is generally very quiet. One Saturday night the neighbors behind had a rousing, late night, but heh, it's Paris and it was a weekend night.
Cons:
- Stale cigarette smoke: there is a strong smell. We had not expected it, and it doesn't go away. You'll of course experience pervasive smoking outdoors in Paris - it's culturally acceptable. Where we live it's a character defect - no one smokes, and people go to great lengths to avoid and discourage 1st, 2nd, and even 3rd hand smoke.
- Clutter: some airbnb places have a good deal of storage for renters. Others don't, and this is one.
