This application predicts the price of a house based on several features.
Please fill in the following details to get a prediction:
- **Latitude**: Geographic coordinate.
- **Longitude**: Geographic coordinate.
- **Number of Reviews**: Total reviews received by the listing.
- **Calculated Host Listings Count**: Total number of listings by the host.
- **Room Type**: Select whether the room is a private or shared room.
- **Neighbourhood Groups**: Select the corresponding neighbourhood group.
After entering the information, click on the **'Submit'** button to see the predicted price.
