My husband and I stayed here for a week while working remotely. The internet connection was great for both of us being on VC calls throughout the week.
Simon & Jerry's home is a well remodeled and cozy home to stay in. They were quick to respond and kindly allowed us to check in early. They even prepared thoughtful welcome gifts for us as we checked in on Valentines Day along with a hand written card. There are security cameras outside the home so we weren't too worried leaving valuables at home. We were pleasantly surprised to find the king bed in the master bedroom to be extremely comfortable (not too soft with just enough support). The robes and slippers were definitely a nice touch to feeling like a fancy getaway. Full sized body wash, shampoo and conditioners were generously provided as well as laundry detergent for the washer/dryer, hand soap at all the sinks and plenty of disinfecting supplies. We appreciated the amount of towels, extra blankets and even space heaters provided in each room. You can tell they really put thought into making their guests feel at home!
While it would be even more convenient if they had a dishwasher in the kitchen, we understand their intimate kitchen space may not have capacity. The water pressure is on the lower side so it can take a bit longer to shower and wash dishes. I think their water pump is what we would occasionally hear at night but otherwise it's fairly quiet. In the mornings, the sun is really bright even through the curtains so bring an eye cover if that might bother you. It was nice for us to wake up naturally to the sunlight instead of our alarms :) We were mostly at home during the weekdays and cooked our own meals. Be aware there isn't a real kitchen range hood to get rid of the exhaust/heat so when we used the oven we had to open all the windows, fan, front door and even AC to try to circulate the air out but the fire alarm still went off on us twice. If you don't plan on cooking much, this shouldn't be a problem.
Regardless, we really enjoyed our stay overall. It is a bit of a drive to get places (especially on the Big Island) so set expectations on getting around (15 minutes to grocery stores, 25 minutes to Hilo). We had a lot of fun when we did go out to explore Volcano National Park, see turtles at Black Sand Beach (we were able to use their beach umbrella and beach mats provided!) and explore Hilo. It is more cold at Volcano (at least in February when we visited) so be sure to pack some layers!
