The place is small but awesome, it has everything you're going to need for a short period of time. The courtyards are absolutely fabulous and if you're lucky and go when the glicinias are in bloom, the smell is awesome enough to stay and live there forever.
Carole is not only nice but warm and she speaks several languages (french, of course, english and her spanish is quite amazing) and that makes any communication easy and fluent. Thank you for that. I'll stay in her apartment 100 times if necessary.
Also, the quarter in which the apartment is placed is fantastic. Two restaurants to go if you stay here: 21G Dumpling and Do et Riz. They are not cheap, but let me tell you something, nothing in Paris is cheap and at least you'll eat in heaven :)
Paris is awesome, and it will be even more if you stay in Carole's place. Enjoy it!
