This studio is really well located in the 6th quarter, near restaurants, supermarket, public transportation, etc. You can easily walk to some great bakeries or the Luxembourg garden. The studio is very clean and has clearly been well thought through to maximize space with a mezzanine to sleep in (beware of height though, no standing!).
If travelling alone with a large suitcase (I was there for a month) take into consideration the 2 flights of stairs.
The tall windows insulate you very well from any street noise, in fact the neighbors are more of a concern than the cars!
Greatly enjoyed the view on the Hôpital Laennec, Paris is so beautiful!
