Flat is on the 5th floor with no lift - and it's the staircase on your right just as you come through the second door (sadly we only realised this after climbing a different staircase to the 5th floor, but that was our fault). Door to the flat was tricky to unlock, but consequently felt very safe once you were inside.
Flat was nice, plenty of light and plenty of space for 2 people. Weren't super sure how to make the bed (there was one thin sheet and then two single duvets rather than a conventional double duvet) but not an issue - bed was comfy.
Bathroom was good - no issues with shower.
We didn't use the kitchen much, but it seemed to have all the usual amenities and was in good order. Good wifi as well!
Area around the flat was super lively in the evening (but no noise in the flat) - plenty of bars and restaurants and Bouabid gave us some great recommendations! Metro also nearby, but it was only a 25-30 minute walk to the Seine so we only used the metro once.
Bouabid was super friendly and communicative throughout!
Nice quiet place to stay, but plenty to do and eat nearby.
