My friend and I booked the Louvre Museum + Seine River tour, but due to the Olympic Games, the river tour was canceled, and we were only informed the day before. Instead, we were offered a bus tour, which we did not want. I tried to switch to a different activity or request a partial refund, but I received no response from Mon Petit Paris. Ultimately, I had no choice but to accept the only option they provided, even though it wasn't what we wanted. Their response time was slow, and eventually, they stopped replying altogether. There was no support or advance notice regarding the change in our booked activity. I would not recommend Mon Petit Paris.
