Thanks for detailed review, I just booked Citadines 11 since location seems great (right near Cindy's, 10-15 min walk to CiB and WN), and reviews look among best in the neighborhood. Hope the situation is still the same regarding guests...
Interestingly, price for my "Executive Room" is now much cheaper on Booking.com (with 10% Genius discount) than on hotel website, 42 vs 72 EUR.
