Eva's Studio B was the perfect size and location for me being a lone traveler (would also suffice for a couple). Checking in/out was easy to follow. I didn't rent a car at all, although, there is a car rental place on the lobby level if you need one. I walked everywhere I wanted to go within Honolulu/Waikiki. I did rent a motorcycle for the day, which is also at street level. Great restaurants within walking distance, and Ala Moana mall is near by too. 7-11 and ABC store is really close. The cheapest bar in the area on the lower level visited more by locals than tourists. I did have a clogged sink in the kitchenette, but that was fixed right away. Eva's response time is the best.
The one thing I might have a gripe about (not the fault of Eva) are the elevators. Luckily, I only had to use the stairs once which was at the time I was checking out. You can easily wait 5-10 minutes every time. The last time I waited over 10 minutes and had to pass up two full elevators since I had a big backpack with me, and a couple with a baby waiting for the elevators before me. Many times only one elevator would work. Sometimes I found it better to go up before going down, just so you can get on.
I would definitely stay in Eva's unit again or even rent out both units with a larger group.
