Traveling in june.
Great location for traveling paris, quite place
Metro is main line or one switch line to the main attractions
Close to great restaurant
At night there is pubs and night places to hangout.
The apartment has everything for you
Just notice few things.
Sofa bed is not so comfortable, especially if it's for long stay. The sammer is coming and apartment is hot until night.
If you're interested to sleep late there is day care next to you.
