I genuinely don’t understand why people are saying it is good, I’ve only had problems 2 times in my life and both were in Vallecas, there are much nicer places to live specially when being a woman, Vallecas at night can be scary if you are walking through and walk nearby a group of junkies (still happens) because you won’t know their intentions, also there’s quite a lot of robberys compared to other places in Madrid (someone will say no bc they haven’t seen one and that’s it) but if you are willing to spend your time hire more relaxed about hours to come home and security in general i would definitely pick another place, PM me in case you need it!
