Wonderful location! So close to the metro and many great restaurants and shops. It's a hike up to the sixth floor but otherwise the apt is easy to access. It is small but bright and has everything you need. One thing to note, the door to the bathroom doesn't close all the way (it's broken, but may be fixed soon?), but it is off the hallway so it still has a modicum of privacy from the bedroom.
Guillaume was very responsive and easy to be in touch with during our stay.
