I stayed with Christina on a business trip. The best amenities for me were: (1) The location - the unit is on a fairly spacious private property. In my coming and goings, not once did I feel I was a burden on her neighbors. (2) Private Parking - the designated parking area is spacious and I I did not have to worry about damages to my rental car.
I have no complaints, but a note that if you are not use to the Coqui, they can be fairly loud when they are nearby. However, they are a nice lullaby when they are farther away.
