Great place to stay for a few days in Paris. Excellent location, near Notre Dame. Christophe met us and was very helpful. He brought us a bottle of wine and fresh flowers. The rooms were very comfortable. As long as you are fine with climbing 4 flights of narrow stairs, then it is ok. Thankfully, there were 2 fans which helped with the record heat. One of the rooms looked over a small street which was very loud throughout the night. It wouldn't have been so bad if we could have shut the windows but couldn't due to the heat. We would definitely recommend Aria & Herman's Duplex!
