I would definitely recommend this place if you're traveling solo and want to stay in Waikiki. It is in an excellent location being a block from the beach and close to some great places to visit. Plenty of walkable stuff.
The place itself is small (the description is upfront about this), but if you don't care about staying in a resort, it's one of the best deals you're going to get. I didn't really spend any time in it except to sleep, anyway, or to have coffee in the morning. It has all the kitchen amenities unlike a normal hotel room.
There are also beach towels, two beach chairs, a cooler, a boogie board, and other beach amenities. I could just pick them up and go without having to spend any money (the rentals can get pricey). So that was excellent.
Thanks, Maurie!
