We had a very nice stay! The appartement is quiet and central, we really had a great time!
Montmartre is your front-yard with lots of tourist activities all around.
A couple of points we came across, just in case you plan your trip with a 4 peerson family as we are:
You live in the 4th floor without elevator
There is only 2 table spoons
No pod lids - in case you want to cook
We had to clean most of the stuff we used in the kitchen before we could use it. There is a oven, a large fridge, various interesting tools but no hand mixer.
2 power plugs (living room and one of the kids rooms) are out of the wall - beware with small kids
The laundry machine is out of Balance - we learned this at 9pm ;-) But it works!
There is no hair dryer in the apparment.
Again, the appartment is great with a spacious living room above the tourist traffic.
