This is a fantastic apartment - super cosy, spacious and comfortably decorated. We loved our stay (for work, two colleagues) so much we have booked it again for our next Melbourne stint. Would also be a great location for a group of friends to stay as has a fab big dining table, kitchen etc.
On a cold weather week I appreciated the bath tub at the end of a long day!
A word of caution that because of the central location, and proximity to many many restaurants, it can be quite noisy throughout the night with the daily garbage, recycling and delivery trucks arriving on Flinders Lane (consistent street noise all night). This is unavoidable in an old building in such a location - but pack some earbuds if that would bother you!
