Boudouin was very prompt in replying all the queries about my questions. He gave a full details descriptions on how to enter the flat as well as direction to go to the flat in full details which I found really helpful as a tourist. The flat is really spacious and can fit up to 6 pax (2 bedrooms with queen bed and 1 sofa bed outside). The elevator in the house is a bit small but that's okay, we do multiple trip to go up with our rock heavy bag. The location is great just few minutes away from Gare du Nord which is the main railway station. There is also Monop which is a convenient store that sells food and other essentials.
