My friend and I spent two nights at Mark and Alex's guest suite, which resembles an almost-detached in-law unit, offering us comfort and privacy.
The unit has everything you need for a comfortable stay-- a nice comfy bed, a sofa that could easily double as a bed (AND an extra bed that you can pull out from underneath!), a table with matching chairs, a kitchenette, a full bathroom (with toiletries), a tv, and beach towels etc.
The guest suite is surrounded by absolutely beautiful garden... if you don't have time to visit any of the botanical gardens in Hilo, just walk around Mark and Alex's backyard :) seriously.
(+) The google map tends to send you to a wrong direction so make sure TO CHECK Mark and Alex's message beforehand. They were really helpful with directions and even came out to make sure we find their house correctly.
Thank you again for your hospitality!
