Location, Location and Location! Mary Jo's place is within walking distance to so many restaurants, beach, groceries. Also, her place could be a perfect base for exploring other places in Maui.
Few things to note, there is construction going on next lot so you will hear machine noises during day time. If you are going to be out during the day then that shouldn't be a problem at all or you can close the lanai door.
Sofa bed can you use some help. It's like a speed table and makes it challenging to sleep.
Overall I would give 5 star to this place. It's a cute little condo and Mary Jo is a great host.
