I stayed in Mark's apartment for 1 week. During my stay Mark responded to each message in a very timely manner.
Issue(s): I only experienced one minor issue with the tub drain being clogged. However, I contacted Mark and the issue was resolved within 2 hrs.
Amenities: I have no major complaints about the amenities. The photos are an accurate and up todate representation of the room. The room is a one bedroom studio with a microwave and mini-fridge.
Parking: There is ample free parking within a 5-10 minute walk. I never paid for parking during the entire week. There's a small parking lot immediately downstairs that can be used to unload large/heavy items.
Area/Noise: The room is on the same floor as a bar. This is convenient but it was loud on weekends. Still, the noise was intermittent and not much of a distraction. The bar (Hula's) is a cool spot for a drink, too. The staff were super friendly and helpful with suggestions on local restaurants, sites, etc.
General: a previous poster mentioned the door / deadbolt. I can confirm that 1) you MUST pull the door close until you hear the door lock click. If not, you can push the door open. 2) The lock is not intuitive, I unknowingly left it unlocked the first 2 days. My suggestion is to confirm the lock is engaged each time you leave the room. (prop it open and try the handle to see if it's opening, toggle the lock on the inside until you get it to work right - that's what worked for me.
Overall:
Highly recommended if you want access to the beach, bars, and nightlife in Waikiki at an affordable price, without sacrificing comfort or cleanliness.
