We found Glasgow Monceau to be just what we wanted, clean, modern, tidy, staff lovely, our room wasn’t a courtyard view as advertised but really didn’t matter to us anyway, and even then I wouldn’t class it as anything worth noting and I’m sure if we’d brought it up they’d have moved us.
Our air conditioning wasn’t working, though that may have been us being unable to work it, haha.
I loved the area in the 17th arr and the Indian restaurant across the road is lovely for an easy dinner. Staff very impressively spoke multiple languages and the room was ideal, the bed was a dream and so comfortable, no street noise. Would definitely return.
For anyone worrying about cleanliness or turning up and having a bad experience, I’d say not to worry about this place, it’s a little gem.
