I stayed in the Oaks on William for 3 nights in the end of october 2013.
The hotel is situated right on the edge of the inner city, but the tram stop is just besides the hotel and everything in the inner city is also in walking distance.
The staff was very friendly and check-in was very fast.
The hotel looked quite new and so did the room - not many traces of usage.
The hotel and the rooms were quiet and one could rest in the night.
Internet could be purchased, but 30 mins a day were free of charge - sufficient to check Emails!
The room was large and had all facilities that one needs in a studio apartment: Fully equipped kitchen (oven, kettle, hob, fridge/freezer, dishwasher, plates, pots, cutlery, etc.), iron and ironing board, safe, free coffee/tea, TV, Radio with Ipod/Iphone port, etc.
Cleanliness was very good and satisfying.
The bed was large and very comfortable.
The bathroom had all necessary facilities including a "waterfall shower head", towels and soap/shampoo/body lotion.
All in all the Oak on Williams is is a very nice studio hotel and offers very good value for money! Next time I come to Melbourne it will be my first choice again!
