I read a lot of good reviews for Hanoi Elegance hotels: Diamond, Ruby, Essence. I reckon I will not go wrong with any one of them, but I'd like to know which one has the best location/centrally located: near the Lake, walking distance to the market? Also, if anyone has had experience in any of these hotels where they allow you to leave your luggage while on trip to Halong Bay; and upon return will allow you to use their facility (to shower, relax) before you board train to SAPA. And again, upon return from SAPA use their facility to shower, relax before going to airport fo your flight....either for free or minimal cost. THANK YOU!
