FabFour is right!
We (group of 8 from UK, Canada, U.S. & Australia) rented 2 apartments last weekend, each with four bedrooms, one above the other and this was ideal for our trip. We were able to move freely between the 2 apartments but each had their own front door and an additional street door.
Appts were spotlessly clean, fully equipped and in an ideal location. Plenty of restaurants etc nearby and close to Metro.
Our host Yann was also fab. Our arrival didn't quite go to plan due to flight delays but communication channels were clear and easy to use and he responded quickly which reassured us that all would be ok!
We had a small problem in one of the appartments with hot water but Yann responded straight away and it was sorted immediately.
Can't recommend highly enough.
