We totally enjoyed our stay at Nishu's place. Staying at Ile St-Louis is a treat. It's not only central, but quiet. Although the apartment is on the main floor and right by the entrance door, it's very quiet. Given the room is on the 2nd floor, the potential noise from entries was not heard. Everything worked as expected and both Marc and Nishu's were helpful and available. It was a treat to be able to explore Paris from here.
