Location, location, location! Large, classy, timeless, comfortable, entire apartment. 5 minutes to West Lake, best well-known place in Hanoi. So easy to get to The Old Quarter, City center by cab, motorbike but I recommend riding a bike so you can get the best feeling. And all the best for Wifi/cableTV/air/heat.
(We stay in our separate floor below you in the same building never compromising your privacy!)
