The location is great. Take bus 21 and 27 that are right outside and you can get to the louvre and chatelet easily. We loved les ursulines, the cafe downstairs. Rue mouffetard was quite the happening street food wise, there is a cool used record store there where I found a 1971 double album of creedence live in Europe. The Jardin Luxembourg is literally next door and I went for a run in the mornings.
