We had a two night stay at Artel apartments and found it to be a fantastic location along Sydney street, walking distance to tram stops and local restaurants. The 1 bedroom unit faced the road which is busy, but we found that the glazed facade cut out most of the noise and did not disturb our sleep. If you would prefer a quieter room ask for one facing off Sydney street - they have a few apparently.
The unit was spotless, with a large bathroom and big shower. There are also cooking facilities which we did not use but would have done had we stayed longer. Check in and out was easy - we did not have a car but there is also off street parking with the unit which is a real bonus along Sydney road. I would highly recommend this place for short term visits to Melbourne if you enjoy being out the city but close to great restaurants and pubs and only a 20 minute tram ride into the city. We will definitely stay again when we are next in Melbourne.
