We stayed in St Kilda over a month. The apartment is charming, the location so easy to trams, beach and cycleways. Although we never met our host during our entire stay, she was always very attentive to our requests and minor problems.
We did experience a few sleepless nights due to the all night parties of some of the neighbouring apartments. Because there is no aircon, we needed to have our windows open most nights so it was quite noisy. Other than that, we were quite comfortable.
Only negative for us, was that the kitchen lacks a good assortment of pots and pans, small cooking utensils for cooking. Due to our long stay, we cooked in most days and found the kitchen limiting for our needs.
That said, we still enjoyed our St Kilda experience.
