Aloha! Sharon's place is pretty much just as advertised. A no frills studio in the heart of Waikiki, it's centrally located to major hotspots and freeway accessible. Be aware that the keycards are very fickle and become demagnetized very easily.
Also, the stove is situated directly below the fire alarm, so make sure that the good fan is on with the windows open. The fire alarm doesn't go off on its own and security needs to come and check the room before deactivating it at the floor's fire panel. The garbage disposal also has a smell of sewage when used. Not terrible, but could have used a cleaning.
As far as the parking situation, there is plenty of overnight spots on Ala Moana that can be a bit tricky to get as the night goes on. Take a quick trip around the area to familiarize yourself with your options and pay attention to the signs as there are street cleanings on Mondays and Fridays between 8:30-10:30am. They will tow you within a half an hour. Luckily, we got out as the last car on the street at 9:00am with just a ticket. $50.
The listing stated that parking in the busing lot was $25. The lot attendant stated that it has been $35 for at least two years.
Also, there is a small TV equipped with Sling, Netflix, Hulu, etc. so bring your logon information.
Other than that, the place was clean if not a bit outdated. But, your not staying in Hawai'i to be in the room.
Mahalo!
