Amazing location! And great views out big windows. Right on the 16 tram line (stop outside the building) to St Kilda beach or the city. Very good location for this price.
On the 9th floor so you could hear the trams a bit but I had no trouble sleeping (I’m a light sleeper). I put my 5 year old in the inner bedroom which was totally quiet. Coffee place two doors down did a good coffee (there was no plunger in the apartment but Paul said he would get one for future guests). Comfortable beds.
If you have a kid, the 16 tram takes you you the St Kilda Adventure Playground, which is worth checking out (opening hours on their website, Google gets them wrong). And trams into the city take you to the riverside Birrarung Marr playground, across from Flinders St station.
