I do not know if Les Jardins d'Eiffel is unique (unimportant to me). It sets a high standard for other three-star hotels to emulate. Typical three-star hotels do not match the level of attention, comfort, cleanliness, friendliness, and service of Les Jardins d'Eiffel. And true to its name, it has a lovely garden!
It was conveniently located within walking distance of two Metro Stations. The neighborhood is charming, filled with restaurants (many cuisines), shops, and necessary services. We could not have made a better choice.
