The location is perfect. It's right in the middle of downtown Sydney and most major attractions are walkable. It's really close to a train station too for locations you'd want to visit that are further away. The place is inside a hotel which actually ended up being super convenient because the hotel restaurant is good and offers a buffet breakfast which we took advantage of on the mornings we wanted something quick. There is a kitchen in the unit but we didn't really use it so I can't comment much on that!
Mirko was also extremely nice and was super flexible with our check in and out times. He met us when we checked in and texted me a few hours later just to make sure everything was okay. He was easy to contact and answered all of our questions quickly.
We only had two minor complaints. The first one comes with the location which we prefer anyways so it's not really a complaint, it's just a comment. The unit was a bit loud. But again, this is because of the perfect location which made it definitely worth it. If you're a light sleeper though I would maybe recommend earplugs. The only other complaint is that we both found the beds a bit uncomfortable. They were slightly on the hard side. Again, this is just us being very nit-picky.
Overall we would stay there again because the location is perfect and Mirko was very friendly and helpful. Thanks, Mirko!
