Gary was very accommodating and did his best to make sure we have everything required for a comfortable stay at his apartment. He sent us a gift on the day we moved out which was very sweet and also let us move out in the evening instead of morning at no extra charge (as a friend could give me a hand moving in the evening).
The apartment is clean and very spacious for a one bedroom apartment. All the furniture are new and everything needed for a short stay is provided (I'm sure if something is missing Gary will provide it for you as soon as possible anyways).
The building itself is very quiet (although, there was some construction work going on during our stay which could be very noisy on some days (during the day), so, if you're sensitive to noise, you may want to check with Gary before moving in).
Location-wise the apartment is very close to CBD and most tourist attractions. The public transport is 5 minutes away (You have to walk down a slope which was absolutely fine by me, but it may be a bit of a problem for some people).

* The only thing that I might have found a bit disappointing was that the view of the apartment is not particularly exciting (both the lounge and bedroom's windows are facing another buildings' windows, located in close proximity).
* If you have a car, check with Gary to make sure he can arrange a parking spot (or a parking permit) for you during your stay, otherwise you may have difficulties parking in this area (CBD is practically right next door, so this is expected).

Overall, I found staying at Gary's place convenient and I think if you're looking for a place close to CBD this apartment can be one of your very good options.
