I have blacklisted hotels of the Accor group for their casual attitude to service and poor, run down accomodation... But he Sofitel Arc de Triomphe is, from my experience, the best top rated in the French capital (probably because it operates as a franchise...)
The location is ideal, in a quiet street next to prestigious Champs Elysees.
As soon as you arrive, luggae handlers run to make you feel expected and welcome. Their class and politeness is very "un-French", that is they are truly welcoming. The check in people are extremely polite andshowing a real care in serving you the best they have. I was impressed they even seemed to recognize me (I went there twice in one month)
The decorum is outstanding: the hotel has just been refurbished by a famous designer...
The bar is manned by first class professional, attnetionate and knowing their job very well. They speak english and french of course. The restaurant is outstanding for breakfast quality and extremely good for other meals. The service is absolutely 1st class and highly professional. I felt welcome, perfectly advised and recognized there too for my 2nd stay... I was very impressed.
The bed rooms are sophisticated and obviously a lot of care has been given to details. I have had once a standard room, which was already highly luxurious and with ample space. I was kindly upgraded on the 2nd stay as the reception head had recognized the fact I had been there a month before and the mini-suite was simply astonishing: a huge bathroom (with a very wide "hammam & shower" where 8 people could easily fit, a romantic tub in the middle and two sinks. amazing. The bed quality is, (at least a good thing from the Accor group) from uncompromising quality.
I warmly recommend this hotel, both for private or business stays. It is the best I have experienced in Paris (and I am in that town2/3 times/month, in the top category, for the outstanding qualty of its service, the amazing infrastructure and its ideal location.
