Ash's place is exactly as advertised. It's a VERY clean, modern, airy loft-type space high above Honolulu. He was very communicative about check-in and and questions I may have. The thing I loved most are the wrap around windows with great views of downtown Honolulu in all directions; this will give you a unique urban perspective of O'ahu that many people don't get.
The only downside was not about Ash, but the building management. The water in the building was shut off at some point in the night and did not come on until the next morning, therefore my sink, shower and toilet did not work. I was assured this almost never happens, and Ash was very helpful and apologetic when I told him the issue. However, the building management could have communicated better; when I asked the front desk what was going on they were mostly unhelpful and told me they did not know when the water would be back on, but that the whole building was affected.
