We loved staying at Katy's. It was close to the Queen Victoria Markets, and within walking distance to the city, and tram. Katy welcomed us early in the day to hand over keys and let us drop our luggage until later check-in time (she was also happy for us to stay or check in early if we didn't mind her working on-site). Katy was helpful with information regarding trams and how to get to places in Melbourne.
The studio is cute and quirky, with a great indoor / outdoor living area. Cooking facilities are basic but adequate, given the fabulous deli's and fresh food available from Vic markets. There are also many places to eat out nearby.
A great space for our family of three to eat and relax after busy days.
