Great little place if you are only staying in Hana for the night. Definitely affordable amongst the other super-expensive options in the area. Beds are comfortable, room and restroom are clean. There is a shared kitchen and eating area, as well as places to sit on the porch. Check-in and out are easy.
However, I will point out that there are a lot of rules. I won't go into them here (as they are explained in the listing), but they did give us a little bit of an unwelcome feeling. There is also no air conditioning (there is a small fan provided), and we were a little warm for most of the night.
One thing to note, which I knew about beforehand and didn't think would be a big deal, is that there is no TV. I didn't think it would be important, but after our long day (we got rained on most of the day in the non-rainy season) we needed to unwind a bit. Practically every food place in town shuts down between 5 - 6 (there is one restaurant open after that, and we found one food truck open until 7). There doesn't seem to be any night life in Hana (especially on rainy days). So, we ended up in our room - wet, uncomfortable, and exhausted - with nothing to do (It was pouring out), and just wanting to wind down a bit before succumbing to sleep.
To be fair, no other place to stay in Hana has TV's (even the resort). I am guessing there is no service there. However, I might suggest just a small one with Netflix or some other basic service.
To wrap up, the Inn was a great price & value, and if we ever end up back in Hana, I would consider staying there.
