If you're looking for an authentic stay in Paris, Cocos room is probably one of the best adresses! I stayed here in February and had a great time.
Communication with Coco was really quick and easy. The apartment is as tiny as described but provided everything you might need for a comfortable stay. Remember that it's located on 6th floor without elevator so be prepared for your daily workout ;-)
It's perfectly located for those who want to discover the city: you have the Metro station Cadet close to the apartment but you also have the Opera and Montmatre within walking distance.
Thank you so much Coco for sharing this special experience!
