The lady who checked us in was lovely. The apartment is gorgeous, absolutely spotless and a generous size for Paris. The bed is really comfy and the sound system is a nice touch.
The location was fantastic. Right in the middle of great bars, restaurants and shops, yet the apartment still feels peaceful. The subway noise that others have mentioned is more like a faint rumble which stops at midnight- which I quite enjoyed anyway. The area feels really safe. There’s also a gourmet grocery store “Epic” on the corner with lots of amazing cheese, if you get tired of exploring the hundreds of great eateries on your doorstep. Most of the major attractions are ~30min walk or you are a few mins from the train.
