Not quite as advertised...
First of all, we did have an overall good time at Mauna Kea Suites. The property is in a great location, very quiet, with beautiful views, and the most incredible night skies. (The night sky views were a surprise, in spite of the reviews. We live in the country with some pretty good stargazing, and we thought how much better could it be? Much better than we've ever seen, as it turned out!)
But, there were negatives...
First, the place wasn't clean. We had to ask the on-site manager (owner? Not sure, she didn't explain) to clean the toilets, which were dirty. She did, but it should have been done before we arrived. Also, many of the dishes were visibly dirty. This is a function of there being no dishwasher in the unit, so if the previous occupants didn't hand wash the dishes properly, that will leave them dirty for you.
Also disturbing was the overwhelming amount of religious items/art throughout every part of the unit, as well as in the outside areas. This feature was so conspicuously absent from the listing photos, and so conspicuously present in reality, it seems to have been deliberately ommitted from the listing. If the listing had shown this honestly, we probably would have decided not to stay here. But we had no idea, so we were blind-sided and just had to deal with it. Not cool.
Another thing not mentioned in the listing was that they have (it appears) three rental units on the property in addition to the main residence. This was not an issue for us during our stay, but it does seem like something people should know when deciding whether to stay here. The listing leaves the impression that there is only the one inlaw unit.
A couple of other minor issues included running out of hot water in the upstairs bathtub before it even filled up, and the microwave oven burning out on us.
On the positive side, we were allowed to check in early at no extra cost, which we appreciated.
In conclusion, this would probably be a nice place to stay for most people, but there are some potential negatives that should either be corrected, or made clear in the listing for this property, so that potential guests can make their own decision.
