During winter time is tough as most of the November temperature was below 0, now is minus 6. Windy and humid as Riga is by the sea
Life cost is Riga is quite high, for an furnitured apartment in center the cost is 1000+, while salary is 3000+
You can find cheaper apartments in suburbs but it's mainly soviet era buildings. Supermarkets have same prices as in Germany, gas is more expensive than Germany.
Regarding people, I am just saying that Latvia is No2 in suicide rates in EU after neighbouring Lithuania
