The stay at Jules was very nice. The studio is small but very clean, new renovated and you have everything you need there.
The location is very good, close to the metro and there are some nice bars and groceries around. You even have a view of the top of the eifel tower from the window.
We just had some communication problems about our arriving time and we couldn't enter directly because the lockerstore was closed already. But Jules was available for us even then in the midnight and arranged a key handover.
