The house you mean is Maison Hai Ly not Maison Thai.
We are sorry that you complain about the price that it is the first time. All our clients said it is a very good value.
For the humidity and damp, the weather in Hanoi was terrible during 2 weeks, all Hanoian have to stand for the humidity and dam, it longs untill today!!!
I hope you had a nice trip in Vietnam!
