I stayed 3 nights in Wellington.
Christophes and Cheryls place is well located, just a short walk to the city. The harbour, Te Papa Museum or other spots are reachable by walk. I leave the car full time in the garage.
The room is very big with much light and a very comfortable bed. The bathroom is modern and just for the guest(s). Both are very clean.
The communication with both hosts was easy and very interesting.
I recommend Christophes accomodation to other guests.
