Me and my mum planned a trip to paris. Our travel agent suggested us the Mercure Montmartre. When we got there, we couldn't believe that this hotel was 3, instead of 4, star hotel. It is a nice, well mantained building, modern enough with many conforts. Our room was double twin with a great view of Eiffel Tower. Beds were ok, bathrooms very well equiped and also very clean. Breakfast was a little bit poor but richer than the breakfast tha I take when I am at home. Its location is very convenient. The subway station is 2 min walk from the hotel and the bus station (where we took the bus "95" that goes to the most important places of paris) is one minute walk only! Despite that mass transportation means were very close to the hotel, I preferred to walk as distances to some important and central locations (Opera,Galleries Lafayette) weren't far at all, even on foot. At nights, I loved visiting the famous area of Montmartre, where u can see Paris from a great view. Montmartre is a great place where french artists are gothered and make portraits and caricatures of visitors.
Generally, the Hotel is higly recommended for its nice location, for its spacious bedrooms, its shiny clean bathroom and its eager to help stuff.

Wife and son travelled to Paris on a Virgin Atlantic package.
Transferred in London for flight to Paris. Arrived at hotel Mercure Ronceray (4 star- "room gauranteed on the voucher")
Lo and behold, sold out! People "did not leave when they were supposed to"
so we put you in another hotel.

The "other" was 6 miles away, in Montmatre (Parisian Greenwich villiage without the restaurants) A real flophouse, complete with recent vomit on the lobby rug. Virgin was NO HELP fixing the problem either.
