Although the rooms are very small, for the price in Paris, it is tolerable. I was afraid that two of us could not leave our suitcases open and still have any room to walk. Actually, there was more than enough room to leave two suitcases open, which is a good thing given there is very little storage space in the rooms.
As to the breakfast, I was very pleasantly surprised. There are both the typical breakfast choices, as well as an Asian breakfast station, which had, according to my wife, who is an expert on this, superb congee.
I found the breakfast ingredients to be superb, in fact some of the best breakfast pastries I have had in any hotel. They have an amazing bread/pastry chef. The croissants were very light. The other pastries were moist and flavorful (which is unusual at most hotels). The cinnamon pastry was exceptionally delicious, but not for the calorie averse. In fact, surprisingly, my only complaint with the breads and pastries was with the basic baguette. Frankly it was very ordinary. There were also some sweet gauffre/waffles that were also excellent. Even the eggs had a certain je ne sais quois (I do not know what) that made them very tasty in spite of the fact I do not really like eggs.
There was a great selection of very good yogurts, butter (next to the fruit and cheese is the really good butter) and cheese. There was plenty of fruit, which was good, but not exceptional, but that is usually the case even in very good hotels, unfortunately.
Although the breakfast dining room is very busy, the staff was very friendly and helpful. In fact the staff throughout the hotel was uniformly friendly and helpful.
And, of course, the hotel is very convenient, for walking everywhere, for the metro and especially for the Air France bus. Plenty of taxis were always outside when needed.
