}
modifier onlyWhileVacant {
require(currentStatus == Statuses.Vacant, "Currently occupied.");
_;
}
modifier costs(uint _amount) {
require(msg.value >= _amount, "Not enough Ether provided.");
_;
}
receive() external payable onlyWhileVacant costs(2 ether) {

owner.transfer(msg.value);
emit Occupy(msg.sender, msg.value);

For anyone getting type error
Solidity 0.8 and onwards ""msg.sender"" is not payable anymore, It needs to be casted in payable first,
owner=msg.sender -> owner=payable(msg.sender)
