We booked Ngan Nga Hotel as a base for 4 days exploring Bac Ha area. Communication with Mr Dong was a bit difficult in advance (we had lots of questions about booking tours, leaving luggage, etc, and his email replies were often just "ok, see you soon". But when we got there, everything was organised very easily. The room (VIP room) was surprisingly big, the beds very comfortable. We were on the 5th floor, no lift! The guide (Cho) he arranged for our 2-day trek/homestay was excellent, highly recommended.
