Very disappointed that we weren't able to experience the holiday we selected, booked and planned for, to stay at Tohapi Paris Nord. A week before the holiday Canvas phoned to cancel the booking due to "operational reasons". As alternative, three other sites offered, we selected to go back to Croix du Vieux Pont. Allocated mobile in Allee des Bremes #6, where early mornings found mains drainage very noisy with air bubbling up into the toilet. Canvas courier 'bleed' the system but problem return in a couple of days. The holiday was a few weeks ago and still waiting to receive Canvas email with a link to their customer review service, so resorted to using alternative means for feedback.
