Place is beautifully located in Montmartre and perfect in size for 2 people. It has almost you might need for some days away, though there was lots of food left in the fridge and the cupboards and wasn't clear if it's for the guests use or not.
Please be aware that the neighbourhood is very vibrant and has lots of young people, meaning that if you want a good night sleep, that might not be possible. Indeed, one of our 3 nights there we slept nothing because upstairs neighbours were partying till 6am. So just be conscious about it it depending on what you are doing in Paris.
Apart from that, place was comfortable, mattress very firm and nice and it was just what we needed for a long weekend.
