Following my mother's advice, "if you don't have anything nice to say..." we rarely write about negative experiences in reviews. The experience we had in this situation, however, should be shared so future potential guests may exercise caveat emptor. The owner used a keypad entry device rather than a key to enter the apartment. Seemed reasonable and very easy to use. However, on the 5th day of our visit, the device stopped working. We later (much later, which is the crux of the problem) learned from the locksmith that the batteries died.
All of our stuff, passports, clothes, medicine etc. were behind a door we couldn't get into. Needless to say, a stressful experience. We reached Shannon and the conversation began with her blaming us for the lock failing. It went downhill from there. After several text messages back and forth that went on for ~ 2 hours (she refused to speak with us after the first conversation), she finally agreed to get a locksmith to the apartment. And, after being told several times that the locksmith was "on the way", he finally arrived. All told, we were locked out for more than 3 1/2 hours. It actually made us question our use of Airbnb because of the sense of being completely out of control of the situation.
We learned from the building manager that this is not the first time the lock has failed and guests have been locked out. To not have a back up key or redundancy built in when using a system that can fail is remarkable to us. Especially after one had experienced it failing already. Through all of this, and to this day, the owner never expressed any remorse or apologized at all for the extremely stressful situation we were in due to her negligence.
We'd like to point out a few other issues as well. We killed several cockroaches through the week. Perhaps that is a common experience living in a tropical space, but it was still disquieting. And lastly, the hot water comes and goes. So, if a hot shower on demand is important to you, this is not the place for you. We took a few cold showers in the late afternoon getting ready for dinner. It is Hawaii, so not the worst experience ever...
