Yana's apartment is a great place to stay while you discover the beautiful city of Paris. There is plenty to see in the neighborhood, or public transport is near and easy to take to visit other parts of the city.
One note- if you have an allergy to cats, it might be a good idea to bring medication. The place was very clean (and the cat was staying someplace else) but it did begin to bother me the first night. However, once I took some allergy meds everything was fine.
All in all, my friends and I spent a wonderful weekend at Yana's. I highly recommend it!
