I am familiar with Citadines and know them as clean, safe, convenient and efficient, if a little unimaginative, semi-hotels with the benefit of a kitchenette, in convenient locations - just what I was after on a recent week-end visit to Paris with my baby daughter. We were spending most of our time with friends who live in that area and so location was non-negotiable. Alas, the Maine-Montparnasse branch was deeply disappointing - really not worthy of the brand. The room at under 25 square m was too small for us to spend any time in, and the furniture was exceptionally drab and tired looking - tobacco-stained wallpaper and smelly grey net curtains, and a very shabby little kitchen. The baby bed I'd requested was a fold-up cot left in the corner - I realised later the reason they'd not assemled it was because there really was nowhere to put it. No sign of the highchair I'd asked for; probably for the same reason. So much for the "baby facilities" advertised. Worst of all was the overpowering smell of tobacco smoke - like very old carpeted pubs in the really bad old days. As an ex-smoker I have a fairly high tolerance of smokey smells but this was bad enough to be unhealthy. An entire can of odour remover didn't make any difference - even the wallpaper stank. Combined with the incessant traffic noise from the very busy 4-lane road on which this apart-hotel is located, which made it unfeasible to leave windows open, it was totally impossible for us to get any sleep. To their credit, staff was very friendly and they did try to find us a quiter room at the back of the hotel (though my request for a non-smoking room was met with barely-concealed derision - we were in france after all) and when I decided to leave after one night with a very grizzly baby on my arm my remaining booking was cancelled with no fuss. Found a perfectly charming quiet little hotel a few streets away where rooms cost the same and were infinitely more pleasant. Definitely not recommended; and especially not at nearly euro150 a night.
