Startup costs for living solo - how much did you spend to get set up?

I know there are a lot startup costs that I need to factor in when considering how much to have saved for doing the program. I am too old to consider living with roommates and will be seeking housing on my own. My preferred regions are Andalucia, Cantabria, and La Rioja. Each one only pays 800 euros. Clearly I will need an abundance of savings to make this work.

For those of you who have already done the solo housing aux life, what were your start up costs for rental deposits, furniture/housewares, utilities/internet, etc. ? Did it end up being more or less than you had planned to spend?
