I thoroughly enjoyed my stay at the Hotel Derby Eiffel. I spend very little time in my hotel when I travel, so amenities such as a pool or gym aren't important to me. Instead, I look for a clean, quiet place to sleep. The Hotel Derby Eiffel was perfect for me. Very clean, very quiet. The location was excellent. I was a fifteen minute walk to the Eiffel Tower, and there were great restaurants nearby.
If you just want to nice place to rest your head at the end of a long day, I don't think that you can do better.
