Catherine is an excellent host and will make you feel like you have booked a 5 star hotel. She had a drink and snack waiting for me on arrival and took time to research some local water fountains I wanted to photograph and made sure I did not get lost.
She explained everything I needed to know to gain access to the flat and then went with me to ensure I remembered and had no problem.
She knows Paris extremely well and will help direct you to great local restaurants that are less expensive than the ones on the main streets.
She made an excellent breakfast for me at exactly the time I wanted it.
