I stayed at this hotel for a last minute trip to Melbourne. Absolutely fantastic for this and the rooms were excellent for the price (think I got a special for $99) They are quite large for a studio apartment and the hotel is new so they rooms don't feature any wear yet. I was able to check in early quite easily and had no problems whatsoever (but to be fair I didn't really have a need for anything other than check in)
For somebody who is not familiar with the city it may be a harder place to find and there is some construction nearby but I did not hear any of this.

For the price and location (right in the heart of the CBD), this place is one of Melbourne's best kept secrets. As it's on a laneway, it's hard to find unless you book the Starbus shuttle, which clearly does a lot of drop-offs in the area. Staff lovely, including the lady who cleaned our room each day .

I stayed at Cube over the weekend with a friend and we were quite happy with our accommodation.

We had a twin room and it also has a small kitchenette. The room was clean and had everything we needed. We wanted to be able to prepare our own meals as my friend has health issues that require her to be careful of what she eats so this was a good setup.

It would have to be the quietest location I have ever stayed at in Melbourne, even though we had a room next to the lift we had no noise problems. I wouldn't class this as a central location, it is a 5 minute walk to central station and there is a tram line about 20 metres away, however the trams at this end of town are not so frequent. The location was fine for us as we were happy to do a bit of walking, but it did feel a little out of the way.

We had the airport shuttle drop us off and we were dropped off in a narrow street and told to walk around the corner to our accommodation. There were building works in Exploration Lane and if I hadn't recognised the apartments from the picture on the internet I probably wouldn't have felt very confident walking through the builders.

So although this was a great place to stay I probably wouldn't stay here again only because of the location and I usually travel with young children - then again there is definitely something to be said for a quiet location!

Stayed here for 4 nights on a short holiday. Thought it was excellent value for money. I think saying they are "serviced apartments" is a bit of a stretch, really the room is just like a hotel room but with a few extras, but that suited me perfectly.
We had a twin bed room. It also had a desk and a small table for 2. I thought the bed was very comfortable, on the firmer side.
You are provided with a kitchenette, which won't be able to cook a 3 course dinner or anything, but was very handy to have a simple breakfast in the morning. There is a small stovetop, microwave, toaster and kettle provided. Much better option than paying heaps for breakfast in the morning. If you were on a budget you could easily make other simple meals.
Location is great, short walking distance to bourke st mall, loads of restaurants, museums and galleries etc. Also can easily walk to most tram lines, and is close to melbourne central train station.
There's still building work going on next door, however we were never there when any of the construction was going on, so no idea how noisy it may be. Certainly it is a non-issue at night and won't interrupt sleep.
Front desk staff were friendly and helpful.
Only issue I had is internet - there is a service there, but it was $11 for an hour or $25 for the day - no thanks.
Will definately stay here again next time i'm in Melbourne.
