I love this hotel when I am visiting La Defense or Puteaux as it is near enough to Neuilly which is a nice residential area and also close enough to the business centre of La Defense. The rooms with a view are great - I got one with a view of the Eiffel Tower which reminds you where you are and is really nice.

The room on 14th floor was large and clean. The bed very comfortable and the facilities good ( including Nespresso machine). Views out to Eiffel Tower impressive. It was entirely functional for business user with good, strong wifi and large desk. I ate in the restaurant and meal was pleasant. The only criticism is it is very over priced! And bear in mind if you arrive at any central station in Paris it will take around 30 minutes in a taxi at around 25 euros. Whilst pleasant I would not say it was worth the money charged!

An overnight stay and very good for the business user. I was given a great corner room overlooking the Seine and looking at the Eiffel Tower. The room was large with everything you would expect from this hotel chain. Unless I missed it, there was no electric outlet to plug in laptop/phone etc. by the desk which is incidentally, a cantilever design so you can have an L-shape work area. The room was very clean and the toilet is separate to the nice shower room. There are plenty of TV channels covering major European languages, a mini bar, tea/coffee making facilities, lots of lights, a nice sofa and a large hanging space.
The check in was quick and the staff were very friendly. Checkout was just as quick. The in room breakfast was disappointing and expensive for what you got - a criossant, jam, hot beverage, juice, small baguette and roll for €16.50.
If you are working in La Defense then I would recommend this albeit a little on the expensive side.

Very poor breakfast, if you want healthy food for breakfast this is not the place !!!! Poor variety of breads, dairy cow products, no fresh juice ... If you eat gluten free and avoid dairy products you're doomed. I gave feedback about it in September they said they would take it into consideration. Several weeks later nothing has changed. Blabla customer service. Breakfast is a nightmare, crowded as can be, noisy and service is terrible.
Room is super basic, poor pillows and rough sheets.
Very expensive for what you get in return and I am an extensive business traveller ...
