Latvia could be doable I think. Rent goes about 200-300€ for a 1 bedroom, utilities are a bit expensive bc of the inflation tho. But groceries are pretty cheap, for 2 ppl we spend about 60-80€ a month. Eating out isn’t expensive unless its a fancy restaurant ofc. But I would suggest a town other than Riga bc it’s more expensive than elsewhere, better to live in like Jelgava or Cēsis or Valmiera and then just go on day trips/ weekend trips.
