The cost of a room in Melbourne Hotel can vary widely depending on several factors, including the type of accommodation, the location within Melbourne, the quality of the room, and whether it is a private room or shared accommodation. As of my last knowledge update in September 2021, here are some approximate price ranges for different types of rooms in Melbourne:

1. Hostel Dormitory: If you’re staying in a hostel dormitory, prices can vary based on the number of beds in the room, with rates typically ranging from AUD 20 to AUD 60 per night. Prices can be higher during peak tourist seasons.
2. Budget Hotel: Budget hotel rooms in Melbourne can start at around AUD 80 to AUD 150 per night for a standard room, depending on the hotel’s location and amenities.
3. Private Room in a Shared House or Apartment: Renting a private room in a shared house or apartment can range from AUD 150 to AUD 400 or more per week. Prices vary based on the neighborhood, the size of the room, and the quality of the accommodation.
4. Serviced Apartments: Serviced apartments offer fully furnished private rooms or apartments. Prices can vary widely based on the location, size, and amenities but typically start at AUD 150 to AUD 300 per night.
5. Student Accommodation: Student accommodation options, such as university dormitories or purpose-built student apartments, can vary in price. Weekly rates for a student room might range from AUD 200 to AUD 400 or more, depending on the location and facilities.
6. Short-Term Rentals: If you are using platforms like Airbnb or Booking.com, private room prices can vary significantly based on the type of property and its location. Prices for private rooms can range from AUD 50 to AUD 250 or more per night.

It’s important to note that prices can fluctuate depending on factors like the time of year (peak tourist seasons or academic semesters may have higher prices), special events, and the specific location within Melbourne. Additionally, since my last update in September 2021, rental and accommodation prices may have changed, so it’s advisable to check current listings on real estate websites, booking platforms, or contact accommodation providers directly for the most up-to-date pricing information.
