My sisters and I had a lovely time staying in Claudia's flat! We felt like real Parisians for a few days - her home is so comfortable and interesting. The location is spectacular. We didn't mind the stairs - in fact, they made us feel less guilty about devouring so much cheese and croissants during our stay! I highly recommend staying at Claudia's for an authentic experience. Five stars! PS I recommend the unique SciFi-themed bar (Bauby Bar) next door for a funky cocktail. Enjoy your stay in Paris!
