Helene's apartment is the best you will find price-wise in Paris.
The location is close to the Abbesse quarter, where you can have an excellent dinner. By bike it is 10 minutes to the Louvre and 20 minutes to the Eiffel Tower. A station of Vélib (bike rental app) for the bikes is just around the corner!
I had a great stay with my girlfriend and can highly recommend the apartment.
The communication with Helene was fast and uncomplicated. The apartment was clean and nicely furnished. We even had a small air conditioner by the bed!
Little cons:
- the apartment is on the 5th floor, so leg training included
- the bathroom is very small -> for tall people it is a little harder to shower, but not unpleasant - Parisian flair included
Restaurant recommendations:
Al Caratello - Italian cuisine
El Jardin d'en Face - very tasty and cheap!
