The unit was cleaned very well, and there were sufficient provisions in the unit for the duration of my stay. It is very modern, comfortable, and bright. The unit is not too large, I think it is suitable for two people, or a couple and their young child. Gwyneth was able to provide a few additional things which I had requested; I was pleased with that as it made my stay even better. I never had the opportunity to meet Gwyneth, but communication with her was quite satisfactory.
The location of this apartment is nicely centralised - nearby are numerous restaurants, mini grocery stores, and it is not far from a main train station, so if you have plans to take the train to the outer areas, you won't have to walk too far. And after you do a day of shopping in the city, you can head back to the apartment, drop off your goodies, and head out for dinner without any physical encumbrance.
Being on the highest floor, you won't get the noise from pedestrians or busy restaurants. However, that is not to say that the unit is completely noise free; you will be able to hear noise from construction (if any is taking place nearby), the occasional bell from trams (not that loud), and I could even hear the intercom ringing from other units, but thankfully only during the day.
Overall, this was a very nice stay, and I would definitely consider booking this unit again the next time I return to Melbourne.
