The location was unbeatable! You can see the top third or so of the Eiffel Tower from the door and it’s just a few minutes’ walk to the Arc de Triomphe and the Metro. It was plenty spacious for our family of 5. The door does open right onto the street, which is kind of busy with people walking past. There is also a restaurant directly across the street that is a little noisy in the evening, which didn’t bother us, but it was noticeable. As others stated, the steps are small, steep, and if you’re tall, you have to duck as you’re going down.
Overall, it served the purpose and was clean and safe, and we would stay again if we were in the area.
