I really enjoyed my two-week stay at Marion's St. Kilda East apartment. As the listing states, it IS very bright and spacious for a one bedroom apartment; in fact, I don't think the photos do it justice - it was actually much nicer than I was expecting.
Whilst the apartment is quiet and private as it's set back from the road, it's within easy walking distance of the lively Chapel Street where you'll find lots of bars, cafes and restaurants (Also Windsor train station which takes you directly into the city centre in 10 mins). A 1930's era cinema is also in this area which was a nice bonus.
In terms of communication, Marion was excellent, always replying promptly; in addition, she was very flexible re: the dates of my stay which I was forced to amend a couple of times - this was a tremendous help. Finally, Marion didn't even get mad when I confessed that I'd forgotten to replace a large box of chocolate cookies that I'd eaten!
I would definitely recommend staying at Marion's place.
