Good Hotel in Hanoi for 1 night

We need a clean quiet hotel room in Hanoi for 1 night. We have stayed at 2 hotels in 2 places that had excellent reviews but were terrible (dirt, insects, noise, etc. ). Any recommendations (we dont care about cost at this point)? TIA

Edit: Thanks for your suggestions! We ended up at LA SINFONIA Majesty with wonderful service, comfortable, clean room and hot shower.
