I recently had the worst experience ever at the Courtyard Marriott Paris Saint Denis. I strongly advise against booking here. I encountered the most unprofessional front desk agent, Nagy. At 10:30 PM, I requested two toothbrushes, water, and slippers through the Bonvoy app. I followed up at 11:30 PM and was told water was available but not slippers, which I accepted. Despite further follow-ups at 12:00 AM and 12:45 AM, I received no response. Being pregnant and extremely thirsty, I eventually had to order water through UberEats, which arrived at 1:15 AM, forcing me to go down to the lobby. There, I met Nagy, who turned out to be the one handling my chat requests. When I suggested he should inform guests if their requests can't be met, he raised his voice and stated I had only paid 150 euros and that water was not included. When I pointed out he had confirmed water was available but not slippers, he calmed down briefly before raising his voice again, insinuating that the service should match the payment. Despite staying at many Marriott hotels, this is the first time I’ve experienced such terrible service. It’s not about how much you pay but the commi**ent to service that was promised. Nagy is completely unfit for his position. Avoid HIM at all costs.
