About 10 km from the touristy area but I was told that it's near the convention centre. I suppose this hotel is mainly for business people rather than tourists. Staff was helpful particularly the young gentleman who arranged a grap transfer for me to go to Hanoi airport. He explained to the driver very carefully where I was going. Thank you so much.
It's a nice place, almost 5 star at 4 star prices. It's great in terms of cleanliness, services, friendly and welcoming staff, and even the breakfast layout!
