I am not a very big fan of Waikiki (too crowded, too many buildings,...). However, Rebecca’s place is a gem in the middle of the city. The neighborhood is very quite. The condo is at walking distance to the beach (5min) and it has lot of extra amenities such as beach toys for the kids, a crib, a parking spot,...
On top of that it is close to the main highways so you can reach all parts of the island in 1 hour with traffic.
We definitely recommend Rebecca’s place and will stay again there if we come back to Honolulu.
