I did not have the opportunity to meet Dianna, but she communicated by text. Her daughter lives next door and checked in regularly. The neighborhood is quiet and dark. Lighting for the BNB entrance would be helpful. There are no sidewalks so it's not conducive to walking or travel other than by car. As soon as you leave the Cove the road gets very busy.
I had to move to Nashville quickly, and I am grateful to have found Morningstar. However, guests should be aware the house is not secure. The key is left in a public place, not under the mat but might as well be. Maybe the poor lighting is purposeful to better conceal the "hiding" place. Any casual observer/neighbor will know where the key is. But aside from that, the main door tends to be unlocked. The room I stayed in had a lock but it was extremely flimsy and could only be locked from (while) inside.
I did not fear for my safety while at Morningstar, but some common sense safety features would have made my stay better.
