Agree with other reviewers that if you're reading this, just go ahead and book now! I spent hours scouring places to stay in this price range, and this was the only place I found that checked all the boxes and MORE.
The location was perfect for all the first-timer things we wanted to do. Very close to major attractions and easy walks to metro stations we needed to use for places we couldn't walk to. Loved seeing the tower lit up at night outside the bedroom window, and enjoyed the view from the other side of the apt on the balcony as well. Well-equipped kitchen if you're considering a longer stay and don't want to eat out for every meal like we did.
We also enjoyed that while this place was close to many cafes, bars, restaurants and attractions, the immediate surrounding area was more low-key and not as crowded or busy as the nearby Saint-Germain-des-Prés neighborhood. This made it a quiet escape from the late-night Parisian bustle while still being close to the action.
As a tip for those who maybe want to stay up late and party more at an airbnb than we did, this one may not be right for you, since the building is old and sound does carry. I would not count this as a negative in any way since we were too exhausted from our long days and long walks to even be capable of staying up late to make noise. We used our stay here mostly as a place to sleep (as should you!), so we had no issues.
