Felt something on my hand and, when I looked, a spider was trying to get inside my jacket. It's 15ºC tonight, so I think the little guy was searching for warmth lol So I went to the balcony, slowly removed the jacket, turned the arm part inside out, and shook it a bit. The spider came out intact. I think it's a type of jumping spider. It's less than 1cm in length and I've never seen any webs in the apartment, even tho I've seen some like it here and there every once in a while.
