Fantastic location, one block from the Odeon metro station and 3-ish blocks from the Saint Michel/NotreDame metro station. There are cafes and bars within steps of your door, which is great when it rains, but rather loud on the weekend, until the bars close around 2am. Do not expect uninterrupted sleep until after 2am (with the window open)
The apartment, bathroom, and linens were all clean. The photos are accurate. When booking, keep in mind that this is a studio and with the couch pulled out, there is very little room to move about. Catherina was very responsive by phone and email, easy to work with and willing to help/offer suggestions.
