@aproposnix Got curious, so had to check what the average cost of living is. According to Numbeo "the estimated monthly costs for a single person are 771.2€ (18,860.0Kč), excluding rent".
Rent for "one-room apartment in the center is 14.000 CZK (560 EUR), in the countryside – 11.000 (440 EUR)" (source: Mezinárodní Svaz Mládeže z.s.).
Net average wage is 1679€ (wikipedia)

So they gave 1 time lump sum for about 4-6 months of living expenses.
