I decided to return from the Routeburn Track a day early to avoid incoming weather, and was able to book Mat's place at 4pm for a 6pm check-in - what a relief, after a long day of walking! Susana was excellent about sending check-in details right away, and even turned on the heat so the unit was cosy upon arrival! Now that's a great host.
It's very close to town, and parking is a breeze - no gate, no code, just drive on in to the underground parking. The unit itself was perfect for my needs. It's compact but super cosy and stylish, and feels like a home away from home. The small kitchenette was great for a simple breakfast in the morning - coffee/milk was provided, as well as cutlery/plates/etc. There's also a microwave, in case you want to re-heat takeaways. Great shower, clean bathroom. The bed was VERY comfy....I easily could've slept 12 hours under the warm blankets, but alas had to move along in the morning! The wooden window shades are a nice touch, and kept the light to a minimum in the morning.
Just for clarification - upon confirming my stay online, AirBnb clarified that there are "some shared spaces". Don't be put off by this - you have the entire unit to yourself! The main entry from outside is shared with one other unit by a small foyer, and you both share the laundry facilities in that space.
Thanks for a great stay, Susana and Mat!!
