Very friendly and helpful staff. They helped us to purchase train ticket from Nantes to Paris which would have been very difficult to do on our own. Excellent service in comparison to another Mercure Hotel in Paris near Eiffel Tower where we stayed on our way back to US. The Paris Mercure is not a quality hotel, poor service, and the bathroom had no accessories, no soap, no shower gel, no shampoo, no body lotion. After repeated inquiry the never provided those during our one night stay. The blamed the house keeping. However, Mercure Nantes Center Grand Hotel has great staff and excellent service.
