This place is in a great location, easily walkable all over St. Kilda. Kitchen is well equipped and some snacks and quick meals were left which was a really nice touch.
As others have mentioned, the hot water in the shower is indeed pretty small in capacity, but I found that turning the shower pressure down a bit made it last plenty of time. The building itself is fairly quiet most of the time, but you will hear anyone in the hallway. The internet was pretty bad, fairly slow and occasionally going down completely. I mentioned this to the host and she said she'd look into it.
That said, this isn't really a place for working from anyway due to the small size and great location - you will want to be out seeing and doing things anyway, and fortunately there are lots of great things to see and do within easy walking distance, or by using the included MYKI card, which was also a great amenity to have.
