I absolutely loved Bi Ecosuites. The hosts were amazing! The building is located in a very quiet and safe residential neighborhood, not far from all the cafes, shops, barbers, restaurants, massage parlors, monuments, tourist attractions. You name it. The room itself was top notch. Very clean, nicely furnished and equipped with everything you would need for a short or long stay. The big Samsung smart tv was great too. I highly recommend Bi Ecosuites while in Hanoi.
