Karli's place is perfect if you want to stay somewhere tidy, super pleasant, and close to everything you want to be close to in the Carlton/Fitzroy/Collingwood area. Local labels, great coffee, supermarkets, and a great subsection of Melbourne's creative community. I was in walking distance of most everything (weather permitting) like Carlton/Fitzroy Gardens, and even the CBD was just a 20-25 min walk through the gardens.
Super quiet and peaceful neighbourhood around the apartment, and close to public transport. Karli herself is lovely, made all the logistics nice and easy and left out fresh towels for me to use. Do note that you will be staying in her day to day home/room, so it's more of a local experience rather than a hotel/BnB vibe. I personally loved that, but something to note.
Overall would really recommend staying for a super lovely and easy stay.
