This place is in the very center of Hanoi. It is super convenient to most of the major attractions and tourist sites. Also very close to the old french quarter market with its hundreds of sales stalls.
One warning about being in the center of Hanoi. The traffic is total madness and you absolutely need to look both ways when crossing the street. It seems the lane dividers are only recommendations and traffic lights are only suggestions.
The building itself is fairly old, but has received a nice renovation. The staff is very friendly and speaks english.
Overall, you cannot beat the quality of the place for the place.
