Claude was a great host. We did not arrive in Paris until late in the evening, but Claude was very helpful in agreeing to our request for a relative to collect the keys earlier in the day. He was very responsive to our text messages.
The apartment is fantastic in a great location in Montmartre, near to several restaurants and shops. It's excellent for couples or a small group.
Only minor complaint is the loud slamming of doors you will hear from other occupants in the building, but that is not Claude's fault.
