My friend Sofie and I stayed at Howard and Joan's for five nights and it couldn't have been better! We were welcomed very warmly and received lots of information to make our stay in Wellington adventurous as well as delicious (great restaurant and cafe suggestions, and recommendations regarding how to explore the city by foot). Our hosts provided a nutritious brekkie every morning and whenever we met in the inviting kitchen/dining area we had lovely chats about our daily adventures and/or shared a glass of wine. The studio is located behind the main building, so it was nice and quite.
If we ever come back to Wellington, we will certainly book with Howard and Joan again. :)
