Mari's place has a beautiful view and really good location for the price. It's comfortable for 3 people and fairly clean and simple.
We did have a couple of issues mainly out of Mari's control. Because the trash room is so close we constantly had a lot little bugs in room when the trash room was open or overfill. Mari did provide some bug spray to help with the problem. The building design, elevators and check-in process was a little complicated and arduous. However parking a rental wasn't an issue and staff there is very nice.
Overall, Mari tried help solve any issues that came up and was very polite.
If you're looking for a decent place to stay within walking distance to many things in Waikiki on a budget, this is a great choice.
