I booked three nights in this hotel. Room was very nice, even the location of the hotel itself (Latin quarter) was very good, very accessible to all important places in Paris. The only thing that needs improvement, I think, is the breakfast, i think the serving time was a little too short, i'm a good eater and i like to take time to appreciate their cuisine.
Also a good restaurant to suggest, very near is le petit troquet, not too expensive and excellent.
I came to the hotel by train and metro but with two children it was a little hard. i used a private airport company for the return http://parisairportransfer.com , and got a reliable service.
Hope it will help,
