The Summer of 2015, our students stayed at the Thai Binh Sapa Hotel. We occupied the whole hotel for about 6 weeks. It was a fantastic stay. The staff and owner were fantastic to work with. The rooms were clean and the breakfast was good.
The hotel is in the heart of Sapa. The hotel is located at the base of the Ham Rong Mountain area; the ticket booth is just across from the hotel entrance. The whole street up and down from the hotel are filled with tourist shops. It is a quick walk down Ham Rong Road to the Notre Dame Cathedral where you can find taxis, scooters, or anyone who will be happy to give you a ride to where ever you would like to go in town or the countryside.
The staff can easily arrange any tour you would like to go on, and the prices were very competitive. They will also give you a lot of great advice on traveling Vietnam.
Wifi is available.
