I had a fantastic stay at Huup's place! Wellington is small, but even so it was an incredibly convenient location, right in the middle of everything and no more than a few blocks walk from everywhere I needed to be for the week (including all sorts of restaurants, the museum/waterfront, etc.). I thought that the room being in the front of the apartment would mean it got too noisy at night, but it was never more than a muffled din.
Also as the other reviews are saying, TinkerBell the cat was a wonderful companion, stunningly beautiful and super friendly - I badly missed being away from my own cat, and she made it a bit easier! Hopefully she'll deign you with her presence. :-)
Overall a highly recommended place to stay, cozy/comfortable/convenient, and Huup was a pleasure to deal with.
