The location was just perfect - very easy to get there from Charles De Gaulle. You can walk 50metres and you're on the café street, close to route de Martyrs etc. 5 minutes walk from Sacre de Cæur.
Such a good location, the room was nice (but if you're allergic to perfume, ask them to remove the very strong vanilla-diffuser :))
The breakfast menu was nice, lots of nuts, eggs, croissants, yoghurt, cheese and stuff :) 12€ each is quite expensive though, but I guess it is because not that many buy it, and they make up a full breakfast buffet :)
We had to ask the receptionist every time we would like a cup of warm beverage which we didn't like, because we felt a little annoying.
