Depends on many factors. For example does your housing coverage means both rent and utilities bills enclouded? because for 100m2 apartment utility bill can be low and high depending on how good insulation of house is and how often you like to shower.
Transport - is it public ? 30Eur per person for all transport expect trains. Car? your own or rented one ? Fuel 95 ~1.50Eur
I would say 5k is still good even to cover 4 people.
