Frank and Vince's apartment is awesome. We loved the South Melbourne location - the proximity to South Melbourne Markets and St Ali's coffee make every meal possibility mouthwatering (to say nothing of everything else Melbourne has to offer!). There are public bike share stations close by which makes getting out to St Kilda/Windsor/into the CBD really easy if you fancy that rather than the tram, which is also around the corner.
Checking into and out of the flat was a doddle, the instructions are super clear, and the space itself is stylish and comfortable. Would recommend to singles or couples in town for business or on holiday. The kitchen is well equipped, the sun terrace is glorious, the bed is comfortable, the showers are great and there's plenty of varied reading material to enjoy in the living space or the study.
Basically, it's great. Do it.
