Mary Toni's place is so great! Very clean and recently remodeled which can sometimes be hard to find. It was a beautiful unit. Mary was easy to work with, kind, and personable. She had some good food and beach suggestions that we utilized and added to our experience. We loved the big walk in shower. We also loved the water and Hawaiian Chocolates in the fridge waiting for us.
Kailua is a great location. Very calm and quite. It gives you a great feel for what regular Hawaii living would be like.
Because it is a neighborhood, you have to be very aware of your noise level after about 10pm. Acceptable noice level is dictated by the neighbors dog, and if he decides to bark. We turned on the AC unit and that drowns out enough noise to not bother anyone every night except one. So it wasn't a problem for us, but if you sit outside at night, or are loud above normal talking voices at night, this might not be the place for you.
Otherwise, we had a great experience and would recommend the unit to others looking for a quite clean place to stay.
