Overall, a great stay. There are some small nuances one should adjust for, but otherwise I highly recommend.
Pros: Central location in HIlo. Megan is a warm and caring host. Apartment is spacious.
Cons: Ventilation is so-so. The walls are also thin, so all street noise sounds like it's right next to you. The shower is definitely a highlight if you're shorter than 5'10". Taller than that, and you can uncomfortably greet fellow guests while washing your hair.
