It was a great place to stay at Kathy's. It was located in the most beautiful suburb of Melbourne—near the tram station, only a walk to Nando's and some street corner restaurants. The nearest shopping center, shops, groceries store, cafes, pubs, clubs, and all of the entertainment in Chapel St. could be reached easily by tram (only 2-3 stops or a 20mnts of walking distance).
Fawkner Park could be one of your best destinations and could be reached in 15mnts of walking features a wide range of sports events, jogging trails, and a place full of greens to sit or have a picnic.
If you're feeling the need for a metropolitan's vibe, Melbourne Central in the heart of Melbourne is reachable by the tram (no need to switch between trams). Hopefully, with all the good things presented in the city, you will find that there's always a home in St. Kilda waiting for your return.
