Bottom line is that there is an abundance of beautiful properties on Curacao and we would not recommend anyone renting a property through this owner.
First, the kitchen was not clean with the refrigerator, microwave and inside cabinet drawers all dirty with food crumbs and spills. This was a minor issue compared to not having electricity or hot water for a combined total of 24 hours. The owner's response was to advise us to sleep outside. He offered no concessions as a result of our experience and refused to refund us one night stay.
The loss of electricity and hot water disrupted our vacation and our peace of mind during our stay for significant periods of time on the nights of Tuesday, 1/18 (several hours until my husband was able to reset the breaker after the owner tried to do so) and Thursday 1/20 (all night). We got fewer than 3 hours of sleep on Thursday night. This is because the lack of electricity meant no air conditioning and no fan were available. With overnight low temperatures near 80 degrees, it remained hot and uncomfortable in the house, even with all the windows wide open and the sliding doors fully opened. Sleeping outside was attempted briefly, but it quickly became clear this wasn't an option unless we wanted to get eaten up by mosquitos. A smaller, but not insignificant added stress was the fact that we had perishables in the refrigerator and freezer and didn't know when/if power would be restored to preserve them.
The owner sent an electrician on the afternoon of 1/19 to replace a breaker and offered to send him back to do additional upgrades (before the all-night outage). We asked the owner not to do this during our stay because we understood that the 1/19 repair to one section of the breaker panel would be enough to keep the electricity running while we were there and because we wanted to minimize additional interpersonal contacts (due to Covid). Had the owner told us, "Well, I can't guarantee it won't shut down again" we would have certainly consented to a proactive electrician follow up visit.
The fact the owner gave instructions to guests (in the on-site printed guide) to refrain from running the A/C, fan, water heater, and microwave at the same time tells us he knew the electrical panel was in need of an upgrade. (We never ran all those items at once).
The owner was pleasant, until there were issues with the property giving the impression he was more put out than we were as a result.
