I've stayed to several apartments and hotels in Paris over the years and Edgar's is definitely the best one.
The flat is big with a lovely living area. Two of the rooms are huge, with really comfortable king size beds and handy details for foreign travelers like usb port outlet on the walls. The 3rd room is smaller but has an ensuite bathroom.
The checking and checkout was smooth and easy. Edgar team was really helpful and gave us a hand with all our heavy suitcases.
The location could not be better, less than 10 minutes walk from Gare du Nord and we could work to our office in rue du Pont Neuf (25min walk)
Fantastic place, We will be back !
