The good: The apartment is in fantastic location! Right across from Southern Cross station, close to the 86 tram and a little walk towards more tram stops. The view is spectacular. The communication from Sophia and her partner was great! They were very quick to respond whenever we had questions regarding the parking, more amenities. The building has a gym and pool which is very convenient. We had to extend our trip and stay by one more day and they accommodated this last minute by letting us stay one more night which was greatly appreciated.
The not so good: The apartment does not have a lot of storage space - for four people visiting Melbourne with an average amount of luggage, this was a bit of a problem. The bedside tables are tiny decorative stools that cannot hold more than a 2-3 items. What would be helpful is having actual bedside tables with drawers for storage of more things that aren't clothes. There were 4 bedside lamps in the apartment and only 1 was working. We were provided one tissue box for 4 people to share and 2 toilet paper rolls - it may be helpful to store some more in the apartment going by how many people are checking in. We also checked in during summer and some days were quite hot and the small AC in the living room would just not suffice. It may help for the host to provide at least a fan in each room to make the stay more comfortable.
The next two things are out of the host's control but should be kept in mind - the building is very big and has many people residing in it; this makes the wait sometimes for an elevator (especially being on the 39th floor) very long - anywhere from 5 to 15 minutes just to get in the elevator and then the wait to get to the G floor or to your apartment floor. Another issue we had was for parking - we paid for a designated parking space for 5 nights. After a long day of travelling we came back and saw that someone had taken our parking space. The host was contacted and they did try to arrange a car towing company but everyone was busy. We were then told to park in another random person's spot and leave notes on both our car and the car of the person who took our spot. Out of the host's control as it's a busy building with many short term tenants coming and going but this can be a hassle nonetheless.
All in all, it was a decent stay and with a few more improvements it can be even better for the next person.
