Staying at Nino's apartment was definitely a good decision! It was just a walk away from metro stations, cafés, restaurants and from the Eiffel Tower! It is also near many markets and it has everything you need if you wish to cook instead of going out. The apartment is cozy and warm, I slept so well that I almost lost my flight.
About Nino... Although I didn't met him in person, he was always very helpful and kind. He answers your questions very quickly.
When I return to Paris (which I intend to do soon), I will definitely stay there!
