This is a very nice beach cottage very conveniently located across the street from Richardson Beach. Remember that many of the cottages in this area were built in the 1930s, and this one has been nicely updated, but it still has some markers of an older building. The windows have gaps in them, for example, so you may see some gecko friends on your sills or in the kitchen (we found one in the fridge and are still puzzled how it got there- he was fine though, we let him out on the back porch and after he thawed a bit he ran away), the shower is a bit small upstairs, and there isn't air conditioning (you can leave the windows open and turn on the fan).
Admittedly, when we first checked in, we were a bit nervous because the gecko droppings look a lot like mice droppings and there was a small ant problem in the kitchen. While normally we wouldn't mind too much if it was just the adults, we were nervous about the cleanliness since our baby is just getting to crawling/walking age. We checked out the downstairs and it was so musty that we decided it wasn't a great place for grandma to spend the night. We contacted the owners about it and they explained the gecko thing (the green ones are pretty but invasive, and they tend to leave bigger poops than their indigenous brown counterparts), and that they had a new cleaner, and that they had just power washed the lanai so the musty smell could be due to that. They came out the next day and cleaned up the ants and gecko poop and opened the windows to air out the smell.
Even after airing it out, we didn't end up using the downstairs because it still smelled a little funny, but they have couches in the living room that can turn into beds. The owners were even kind enough to let us check out at noon (late checkout) because we had a very late flight on check out day (they explained that they would have let us do it later, but they had a cleaning person coming and she needed 4 hours to clean before the next people arrived).
Richardson's famous black sand beach is across the street which was a real treat, and baby particularly liked watching the tour buses come and go from the screened in lanai. For small kids though, I'd recommend going slightly down the street to Leleiwi beach - they have a nice set of stairs and very shallow little pools that are very calm. Richardson also has some pools but it was a little too rocky in most places for baby.
