My wife and I stayed in Paul's guesthouse for one night while in Wanaka, and shared the building with another couple who were in a separate part of the house. Even though we technically didn't have the whole space to ourselves, it felt really private and secluded, and had lots of space to relax in. Paul very kindly lent us both mountain bikes too to cycle around Wanaka which really made our visit special.
Look no further for your accommodation, you've found it.
