My husband and I stayed in this little studio cottage for the first leg of our Hawaiian vacation. The location is great- you can walk to the Poipu beach, which is a really beautiful beach. The owner even provides a cooler, beach chairs and pool towels for you. There is a grill and small kitchen to make breakfast or whatever meals you need. No A/C but the owner provides lots of fans to help cool it down and move air around. If you're gone most of the day like we were (and you should be, its Hawaii!) then it's fine at night without A/C.
However, the parking situation is complicated. At night, you have to park on the side street, which is totally fine if you could walk through the side yard of the front house (which is also a vacation rental). BUT, the instructions explicitly tell you not to. Instead, at night, you are supposed to walk several blocks around the corner-in the dark-to the other entrance. The owner provides flashlights (one was working, one was not), but still. IMO, this is a HUGE liability for the owner of this property. If something happens to a visitor because they have to walk several blocks around the property, late at night, then I would think they have a very valid claim against the property owner. I also don't see why it should bother the renters of the main house if a couple is walking to the back property. Afterall, the main house guests get to use the pool, which can be a bit intrusive on the pool cottage guests, so why not allow them to walk through? Strange.
Would definitely rent again, but would still ignore the instructions about walking around the block and would just cut through the side yard of the main house.
