It depends on your expectations of lifestyle really. For some this would seem a very comfortable existance but for others may seem very low.
The housing section is ok as long as it is large enough to suit your expectations for something suitable for your family. Most accomodation provided in in the form of apartments and sometimes they are quite small so this may be an issue if you are used to a house and yard etc. In summer your kids will be indoors 100% of the time due to the heat, so this is something to consider as a family. Having a car provided will be very helpful and is not that common here as far as I know. If you wish to let us know what country you are from etc it may give us a better opportunity to let know know if Qr6000 will provide you with the type of food, entertainment and clothing etc you are used to. Best of luck
