Pros:
* The neighborhood (14th A.) is mostly residential and so provides an "authentic" Parisian experience.
* Excellent location within the neighborhood - walk out the door, take a right, and within your first hundred paces you pass a patisserie (beautiful breads/pastries and cakes), a boucherie (wonderful aroma of chickens and potatoes roasting in a small oven outside the front door), a bistro that serves only fish (Le Bistrot du Dome - a must if you like seafood). Take a left and again, within a short walk you pass a couple of boulangeries, a great Italian butcher/cheese shop (great sandwiches), a fruit/vegetable market, a small "super market" (very helpful and convenient) a wine shop and a few cafés. You could spend several days just eating and drinking on this one block of rue Delambre and have a great experience. Get to one end of the block and there is a stunning farmers' market (on some days) and the gateway to the southern part of Montparnasse, at the other end of the block are famous brasseries/cafes (le Select - good, la Coupole - big, classic, famous) and a jumping off point into St. Germain.
* Sebastian and the rest of the staff at the hotel are very helpful in reserved sort of way (think of waiters who are attentive, take care of any request, but otherwise don't interject themselves into your dinner.) I do agree, however with the comment above about one of the night desk guys - on the first night I asked him if he thought a particular restaurant up the street would be good, and if he could recommend someplace else in case we couldn't get in - his response was essentially "its fine, you can go to any of the cafes/bistros up the street, they are all good enough for you" (which is not true). Not a big deal, just don't look for this guy to be helpful.
* The room was fine, clean, perhaps small for American standards but typical of rooms in Paris and certainly big enough. We had a room with a balcony on Delambre, which was a huge plus.
* Typical comforts are all there- free tv & wifi, good shower, mini-bar (with reasonable prices) , comfortable bed/pillows/linens
* Lounge on the first floor is an "honesty bar" - go behind the bar, help yourself to a drink and mark it down. Comfortable, almost always empty and a nice place to have a nightcap and skim the travel books to come up with a game plan for the next day.
Cons:
* The comments from other reviewers about the occasional street noise at odd hours were true (i.e., you could hear the trash pick-up on a couple of mornings; on weekends young people singing in the streets loudly after the bars closed), but don't get the impression that this is a "noisy" street. It's pretty quiet actually, with relatively light car traffic, but with the narrow streets, loud noises are amplified. This would be the same pretty much anywhere in Paris - nothing "uniquely loud" about rue Delambre.
* Regarding the comment about security and leaving the key at the front desk, it is a good point, I suppose some thief could try to get your room key, but this seems very remote to me. It is a small hotel and the folks at the desk seem to be aware of who is in what room. In any event, each room has a safe and you set the combination yourself.
* If you are looking to spend the bulk of your time at the more famous tourist spots (e.g., Louve, Eiffel Tower, Notre Dame) I would think you would want to be closer to the Seine. read more
