Overall, we had a lovely stay at Ran's. The unit was just as cute and cozy as the pictures depict and was located in a safe and convenient area (equidistant from downtown Waikiki and Ala Moana Center, about a 15min walk each way) . Ran was responsive to all of our messages and the self-check-in and self-check-out process was smooth. Our main concern during our stay was that the window lock was broken - there were a few windy days where the window kept blowing open on its own (it's a slide window, no mesh screen) so we had to keep manually closing it but this was impossible to do overnight. The streets were quite noisy and the pigeons in the morning were like roosters, so our sleep was cut short. The air conditioning machine was also quite loud and would intermittently turn on and off in waves so it wasn't a background noise you could get used to. Our greatest fear was the potential for bugs/salamanders to crawl in when the window was open overnight but thankfully we did not have any unwanted visitors. Ran was made aware of this issue and hopefully it will be fixed soon!
A few things to know about the building - it is an older building so the elevators took quite some time (1 of 3 were broken during our stay so it took even longer). The building also appears to predominantly cater to airbnb units so you'll see many visitors like yourself. They have a car rental service on the ground floor as well as a baggage storage locker service ($5/bag/24hrs) with security on the lower level. Parking was $40 for one day with a subsequent $5 discount with each additional day.
