 None whatsoever everything just perfect 
 We loved our beautiful suite at Hotel Sainte Petersbourg Opera it was quiet peaceful soundproofed everything was so comfortable and spacious The staff were welcoming and helpful and we would definitely stay here again The position near the Opera the Roissy CDG bus my favourite Fauchon lots of lovely restaurants and bars was perfect Easy walking distance to everything we wanted to see on this trip which is about our 5th to Paris Sadly we were there during the Friday 13th Nov happenings and we felt so dreadfully sad for beautiful Paris It will never stop us returning to this lovely hotel though and recommending it to friends who travel
