I've stayed at the hotel with my wife at the beginning of November 2012 to participate in a trade show that was happening in Paris. For 2 consecutive nights while I went out to have dinner someone entered in my bedroom (proved by the Hotel access log) and stole several items (credit card, clothes, gifts, perfums, ...).
The only thing that the hotel offered to support the problem was the address of the closest Police department to communicate officially the problem and a new room in another area of the hotel.
I've requested a feedback from them for the actions they would do to solve it, but no feedback was given.
At the same time I discovered that the Hotel is not safe (no security cameras in the corridors, no controls on the employees, ...). I informed my company (which selected this hotel) and we will no longer stay there. I've also informed some other companies and they probably will not select this hotel again.

So, be aware, YOU ARE NOT SAFE AT THIS HOTEL!!!!!!!!!!

Our stay was excellent stay. Big Rooms with a kitchenette and a vast bathroom with a big tub. the bed size was too small (Double bed rather than queen) and the mattress was a bit soft. We enjoyed the hotel, gym, friendliness of the staff, and the cleanliness. I read that the decor was on the old side, which was not true, rooms dont feel old at all. They were modern and practical. The location is unbeatable with plenty of things to do around, good restaurants, cafes, museums, scenery, English cinemas, etc.. We would definitely go back again.

Great serviced apartments , amazing staff thanks to Heidi and Stephanie. They told us how to be local when gong to Reims, organised our Opera tickets and we are grateful we spent our money on Figaro rather than Moulin Rouge. Since we were revisiting our honeymoon in paris on our second anniversary we really enjoyed citadines - our first stay there.
Immaculate, spacious rooms, great separate kitchenette again very clean, daily housekeeping with weekly vacuuming . The nearest metro is st German but we only went there when we landed in Paris and took the metro in. It stinks! So does most of Paris of human Wee. Shame really. Go over the Pont Neuf bridge and take the metro on the other side like Chatelet or Les Halles.

We would definitely recommend Citadines. And look forward to going back again. Couple from Sydney Australia.

Location is good in the Latin quarter near fun alleys with restaurants shopping and people watching. Our room nice but funny because it's long with toilet-kitchen-living room-tub/sink-bedroom so if you go to the bathroom and need to wash your hands it's not in the same room. Heated towel bar is nice and bed comfy. Nice soaps and lotions. Staff is matter of fact and not good for recommendations at all. We used American Express points so was neutral on the value--free is amazing
