Check-in process: They sent a notification on the process and contact. Overall the process was very simple and easy. There is a security individual at the entrance and if you follow their process, then there should really be no issues.
Interior & Amenities : The place is just as the pictures show. They have all the essentials ranging from cooking items, ice machine(in the fridge), washer & dryer, iron/board, towels, shower supplies, etc so you should be able to just unpack and go explore. My stay was a week so I started off bringing some additional supplies(ie shampoo and such) but they have the starter supplies for sure. I had a parking spot on the fifth floor(gated garage) that could fit 2 but I only had 1 vehicle so no issues. WiFi...just read the info on the router in the bedroom and you're set. I used it to do some work e-mails and also stream some videos from my phone and had no issues.
View : You see the ocean...need I say more? You can also see pedestrians on the main strip if you enjoy people watching. The veranda(lanai) is over the community pool and hot tub below(which you can also access).
Location : You are one block behind the main strip of Waikiki(shopping) and two blocks from the beach so you can easily walk to anything you need. There are little convenience shops all over the place, shopping malls and boutiques, and rental places for your enjoyment......all walking distance. With a car, there are malls and grocery stores all within about 3-4 miles.
Tourist Tips : I rented a car so I drove east from Waikiki and took the coast road north...found a really great mellow beach by something called chinaman's hat and also a great tour at kualoa ranch (where they shot Jurassic Park and other movies).
Check Out Process : again, with their instructions it's very simple.
Thanks!
