Casper's apartment is charming and in a vibrant, beautiful and well located neighbourhood. like most apartments in Paris it is very cosy, but light and airy. we were okay staying with our 5 year old and 9 month old but hadn't realised there was no door between the living and sleeping areas...it was OK, but something to note if you are traveling with young children.
Casper and his housekeeper were both very accommodating and had communication.
Coffee, tea, fruit and juice were awaiting us... such a nice treat after a long journey.
