Looking for a reasonable short stay apartment or reasonable hotel suite for 3 adults in Melbourne for lst week in October which it turns out is school holiday time. Want to stay under $200 night. Any suggestions appreciated.
I stayed at the Mantra Southbank last year, which is a hotel / serviced apartment set up, so you get a dining room / breakfast room downstairs, and our room had a kitchen, lounge room, bathroom and separate bedroom. I expect there are other configurations. It was very convenient for our small family. It is a short walk to the Yarra, and you can cross the footbridge to Flinders St Station and from there get into the city (main shopping precinct) easily. There is also a small supermarket about 500m down the road, and a parking garage if you bring a car. There is also a small shopping centre nearby (not groceries but restaurants / boutiques) on the banks of the Yarra.
You could try Citadines or Punt Hill Apartments. They are both chains and have a few locations in the city. We haven't stayed at any in Melbourne alamo rent a car minneapolis airport but stayed at Citadines in France and they were fine.
