Mark was very helpful with any questions we had and was quick to respond. We stayed at the Grand Waikiki suite 412 and the owner Robert was welcoming and let us into the suite early in the morning and advised us that he was available to assist us with any questions if we needed. Throughout our stay we were given privacy and not bothered at all. Great location, room offered everything that we needed. There is a bar a couple of floors down which plays music till quite late so if your a light sleeper this may cause you some annoyance, but not too bad (nothing some ear plugs can't fix) and the location makes up for it. Highly recommend this location and dealing with Mark and Robert was a breeze!
