First off, the room is a good deal, and it was very fortunate that I could secure it at relatively short notice (about a month in advance) for a decent amount of time. There are a few minor letdowns - firstly, the room can be quite loud as it faces a main arterial (Dandenong Road), and the traffic noise (and light) isn't well-mitigated by the window; and secondly, the shower needs a bit of TLC as the floor tiling seems to be a bit run down.
Despite that, Ivy is a responsive, friendly host, and the location is primo - 5 minute walk to the Carnegie Station, shopping centre, and the rest of Koornang Road. Very easy to get in and around Melbourne from. Would recommend for short stays.
