Just spent 4 nights in "Le Marquis" and had a very nice stay. It's a clean, modern, well-situated hotel with excellent and helpful staff. We asked for restaurant recommendations several times and they came up trumps for us.
The rooms are quite small, but this is common in Paris apparently. The rooms are not as "boudoir-like" as the hotel would like you to believe. We were staying in room 304 and it looked like any hotel room in Paris (with 2 furry cushions!) The photos on their website are a little misleading. It's actually more modern than you might like.
There's a very well-stocked supermarket across the road, selling (among other things) excellent and reasonably-priced champagne (Taittinger 23euro, Laurent-Perrier 26euro). An excuse to drink more I think! There's also a wonderful boulangerie next door to the hotel. Pick up your pain-au-chocolat and eat it in the nearby park under the Eiffel Tower. Wonderful!
Nearby restaurants worth visting are Pere Claude (try the creme brulee) and Le Suffren.
I would not hesitate to stay in this hotel again.
Be wary of cab drivers though. The front desk in the hotel told us 50-60 euro for a taxi to the airport. It actually cost of 64 euro, incredible. We queried the fact that the taxi driver already had his meter running when we got in the car. This would have been so bad if he had not used the hotel's toilet facilites while we waited in reception and our meter was running outside. We were stunned, but didn't want to cause an argument as were running short on time. The taxi driver explained that because the hotel booked the taxi by phone that morning, the passenger must pay for the cost of the driver getting to the hotel. An opportunity for ripping people off if you ask me, it was already on 10 euros by the time we got in the back seat.
(If the hotel is reading this, and the driver was doing anything untoward, the taxi number was 789)
If you can, take the train to the airport and save yourself a lot of money.
