Thi Minh Hien was a great host!
She pretty much has an apartment complex in her basement where she can host I believe 3 different sets of guests (3 bedrooms and a communal kitchen). My husband and I had an besuited bathroom which was perfect for us. And if there were other guests, we never heard or saw them.
We met Thi Minh Hien along with a few members of her family once and she nicely let us know they were having guests for the afternoon and when to expect everything to quiet down.
While her home was a little further from popular attractions (roughly 15-20 minutes each direction) we enjoyed our stay!
