Kate's private apartment in Kelburn was fantastic and complete with terrific views of greater Wellington. Kate was very responsive to communication and was actually overly concerned that she would be out of town for our arrival. Needless to say we encountered no problems finding the apartment and making ourselves at home. The coffee burr grinder was an especially nice touch. Would definitely stay again and recommend.
NB: We did not have a car this trip so I can't comment on parking; we walked down to the city in the morning and for dinners and then either rode the cable car, an easy walk from Kate's or caught an Uber home.
