We spent one night here and enjoyed our stay, although the experience started off rocky to say the least. Once arriving in Paris via a late-night, high-speed Eurostar train, all we wanted to do is check into our room and go to sleep. Unfortunately, the hotel had overbooked, and those of us arriving after 10pm no longer had a room to check into. Guests were re-routed to Concorde's sister Lafayette property, also on our recommended list, but far across town and not where we wanted to set up our Paris "home base." After arguing with the night-shift staff, we requested to be booked into the Le Meridien hotel (located across the street) for the night. Despite some resistance, our request was granted. After this annoying experience, our expectations significantly diminished for this property. However, to our surprise, Concorde Montparnasse impressed us through the following day and night. Rooms are small-ish (with tiny televisions), but not overly cramped, we've been in smaller. But, the mattresses are very comfortable, sheets and covers very soft, and the shower/bath water pressure very good. While one side of the hotel enjoys views of the Eiffel Tower (on a clear day), the downside is the traffic noise from the street below. Our quieter room overlooked the courtyard rather than the city, definitely a better choice in our opinion.
After a long day of research, and walking, and a late night before, room service and an early turn-in sounded good. The food delivered to our room was fantastic: Steamed vegetables that tasted as if they were just picked from a garden; tasty entrées cooked with fresh ingredients; and, oh that bread! Each morning, a continental breakfast is served including an assortment of cold deli meats, cereals, sausages, breads, juices and coffee. It's nowhere near as impressive as the room service meal, but if you can package it with your room rate at a discount, it is worth the convenience.
The lower level hotel gym is a tiny room housing four cardio machines. The cherry hardwood floors and mirrors adds a little charm, but just a little. A treadmill is available for runners, however a better bet would be to jog to the nearby Jardin du Luxembourg, the largest park in the city. Vision Fitness equipment is inferior to Precor, Technogym and Life Fitness, so keep your expectations in check. The spin bike is likely your best bet. Those desiring a more serious workout can walk ten minutes to Club Med and lap swimmers can hoof it 5 minutes to the Piscine Armand Massard. After the initial headache, Concorde Montparnasse redeemed itself and we would stay here again.
