I have lived abroad in 6 different rental apartments and suffered some unfortunate incidents, though none of them felt so bad that I was hoping to be back in Finland.
Below I listed the incidents, I have faced
1. Water pipe broke and the apartment was flooding2. Cockroaches disturbing the peace at home. Getting rid of them was challenging
3. Contsructtion workers in the neighbor made a hole to my living room wall
4. Electricity cuts few times but just for few hours
5. Mold getting formed to the walls
Here some common incidents what I have been able to avoid
1. Getting robbed
2. Getting scammed when renting a flat. I have always been able recover at least 50 % of the debosit.
3. Bringing bed bugs home
4. Extremely high electricity bill. Many people who are not aware of the costs of heating/cooling in Spain get surprised for the cost.
5. Flatmates who are impossiple to live with
