We had a wonderful time in Waikiki. The location is great. We walked to the beach as well as to shops and restaurants. The Waikiki Brewing is a stone's throw away. I will say that we also drove to the other end of Waikiki beach to check out that end of the beach. It is too far to walk all the way to the south end of Waikiki beach (at least for us) but the stretch of Waikiki beach closest to the Airbnb is easily walkable which we did several times.
We went on several hikes including two with waterfalls, one of which we swam in. We took a day trip to North Shore which was amazing. Went to a Luau. Went snorkeling. Did Pearl Harbor. Overall an amazing trip.
The Airbnb is very much as advertised. It has a great view of the canal which is the best view for this building since you can't really see the beach from the other side of the building anyway.
The street noise isn't bad except for the emergency vehicles which seemed to come by an inordinate amount of time. I appreciated the security. You can't enter the building without a key and you can't use the elevator without a key. The unit is clean and everything works. The only thing I'll say is that this Airbnb is very basic and no frills.
