In terms of location, this studio is absolutely ideal. Many major sites are easily walkable or available by the metro, and several fun, less tourist-heavy neighborhoods are close by.
As noted, the studio is small, but the space is very well utilized. The kitchen is nicely equipped to do some cooking, with multiple grocers nearby. Having laundry in the apartment is a nice bonus. It was ideal for a two and a half week stay -- easy to get work done, but also fantastic to step out and enjoy Paris.
I'm looking forward to staying here again!
