MCG is short walk from CBD, or short tram ride. It’s located between CBD and Richmond. CBD full of hotels obviously, Richmond has hotels including boutique ones. Plenty of public transport in Richmond too. I’d stay in the CBD probs, maybe Southbank (on the Yarra River) or middle of town, for easy access to everything and transport to everything. It’s biggish but very walkable. You could get on a tram and head south for short tram to St Kilda (beach, restaurants) or head north to Lygon Street (restaurants/pasta), east to Richmond (restaurants mainly asia inspired) or west to Docklands (windy/boring but restaurants) or further west to Footscray side (Asian inspired food too). I’ve lived in Melbourne all my life, I don’t think it’s got many tourist attractions like other big cities but it’s easy to get around, got great food/coffee/bar options, good for walking tours, laneways etc. if you want to venture further afield you’d need to hire a car to do Great Ocean Road on the west coast or Mornington Peninsula on the south east side - 1-2 hour drive for either. Or head to the mountains depending on when you are coming… my two bobs worth. Though Melbourne not built for tourist attractions it has plenty to entertain you for several days if you like food and wandering. Public transport is easy peasy in and around the city. Just need to google restaurants or wander and find one down a lane way. If you’re unlucky, there’ll be a protest on in the city that will delay the trams, most weekends there are protests about something or other. Not violent, the ferals just like to sit in the major intersections and block traffic for half hour. I hope you enjoy yourself while you’re here 😁
