I was staying in Honolulu mainly for a conference and think Maria's appartment was perfect for that occasion. It's really close to the convention center (10 min or less to walk) which was very convenient. To the beach at the Hilton Hotel it takes also about 10 min. The appartment is very well equipped and also nicely decorated. The bed was very comfy. I also loved to find an ukulele :-)
One thing you might want to know: the curtains are not really light-blocking, so I brought a sleeping mask.
I also appreciate that Maria gives the opportunity that you clean the appartment yourself, so there's no cleaning charge on airbnb. I didn't have enough time, so I payed for the cleaning, but I think it's a really nice offer, especially if you're planning to stay longer.
