My sister and I were in Paris for a wedding in the 15th, which made Isabelle's place the perfect location for us, as it was walking distance to the church. It's also across the street from a lovely little bakery where I practiced my one French sentence ("Je voudrais un pain au chocolat.") every morning.
The place was spotless and the pull out couch was just as comfortable as the bed. We really only used the kitchen for fridge storage and making tea, but it was well equipped had we chosen to be more adventurous.
Isabelle's support team was great at communicating and check-in and check-out was a breeze. We would definitely choose to stay here again!
