I stayed with my family of four, including two young children. The location was clean, the staff was helpful and polite, and the room was very comfortable. Despite large crowds and loud soccer events outside, we could barely hear a thing from our third-floor room — the soundproofing was impressive.
The location was excellent, within easy reach of Notre-Dame, the Louvre, popular shopping streets, and the Metro. The only minor drawback was limited storage space, though that’s fairly typical for Paris hotels.
