My family of 5 stayed for 2 nights before Christmas. The apartment is lovely, clean and well set up. We were there on the hottest day in December in Melbourne (44 degrees ) and the air conditioning had no trouble keeping the temperature cool and comfortable.
Beach is right across the road and you can walk to all the St Kilda attractions. Parking on the street was easy to find. Quiet for sleeping too. A fantastic place to stay. Enjoy!
