There are 4 hotels in the Prince chain, so you may be moved depending on availability of room. But, we stayed at 8 To Tich Street in Hanoi Old Quarter, fantastic. Staff, especially Viet and La were amazing, went above and beyond to help in any way they could. The staff here also speak either exceptional English or French. Book tours through them with confidence if you're keen to go to Halong Bay or Sapa. Definitely would stay again.
