Great hotel in a great location
Had a great long weekend based at the mercure gare montparnasse. the room wasn't massive but certainly big enough for a long weekend, well maintained and clean. breakfast seemed to be a bit of a hit or miss with items not being replaced consistently or indeed quickly but when there, a good selection of goodies to choose from. the hotel is very well situated just a short walk from gare montparnasse but in a street that doesn't suffer from a lot of vehicle traffic. also within a very short walk are some excellent restaurants - charlie birdy and hippopotamus are two that are well worth the visit. it's not a huge hike to the usual tourist attractions - we walked to the eiffel tower, arc de triomphe and down to the louvre on the first day but wimped out and used the metro on the second day for musee d'orsay and notre dame amongst others. being close to a major railway station is very handy due to all the different metro lines that converge there. this does however bring it's own problems in navigating the underground mazes as the metro staff are worse than useless and actually manage to be actively unpleasant. i guess it must be the subterranean lifestyle. all in all, definitely should be on your list of places to stay to consider when you visit paris.
