Small, but very well located apartment in an area close to Notre-Dame with plenty of restaurants and bars. The bedroom is on the backside so no noise at all at night. Bed is comfy. All in all a good stay with good communication and easy check in.
Yes, apartment is on the 4th floor but it was not an issue for me.
Could be a bit cleaner, but that is a minor thingy. Would come again i suppose!
