Timo's place is in an excellent location (5 minute drive to Downtown Hilo, and a 7 minute walk to the nearest 7-eleven), and it is just the right size for one, maybe two, people. Both Timo and his wife are super-friendly and helpful, and they're always up for a chat or hanging out if you want.
It gets a little hot in the room during the day, but they have a little fan that you can have going, plus they have a screen door so the air can circulate that way too.
They have a big shower space, and I really appreciate that! They have one mini fridge and and one mini-mini fridge, which was enough to keep food for a couple days. Tap water isn't cold (in Hawaii in general, I noticed), so I always had one plastic water bottle filled with tap to keep in the fridge, so I had access to cold water. There was a kettle too, so I was able to have tea/water/ramen easily.
At night, the coqui frogs are loud, so if you're sensitive to sound, you should bring ear plugs (and they also provide you some if you forgot). And the chickens might wake you up in the morning. Sound doesn't bother me so I was fine with both, but I can see why someone may have a hard time sleeping/staying asleep if they're not used to it.
If you're traveling solo and looking for a place that's close to downtown, his place is an excellent spot!
