Thierry’s place was absolutely amazing for our 4-day stay in Paris.
The flat had everything we needed and was located in the prime 4th Arrondissement right next to multiple sight seeing locations, including Notre Dame of course.
The Île Saint-Louis is full of cute shops with a supermarket less than a block from the apartment.
As a heads up, the flat is on the top floor and there is no lift, so pack wisely (no bigger than a carry on size bag recommended as you have to take the stairs)!
Highly recommend Thierry’s place to anyone looking for great value in staying close to downtown Paris.
