Mark's apartment is just ok. We found it very clean and perfectly located in Waikiki, at 3 minutes walking from the beach. It is located on the part of Waikiki close to Kapiolani beach park - the part I like more. No problems at all with the check in - the manager was there in person. We had a small problem with the tv (our fault, we just were not able to use it) and they fixed it in less than 24 hours. There were 4 of us in the apartment (me, my wife and the two kids) and we could fit. I warmly recommend Mark's apartment if you're planning a vacation in Honolulu.
