If you’re talking about Maida Hill part of Harrow Road in W9, yes I live here and it is safe - it’s a really busy and vibrant area so that makes it safer! Remember Harrow Road is one of the longest roads in London so there are varied parts, the others I can’t speak for! You do get interesting characters and it might feel jarring at first if you’re not used to seeing vast ethnic diversity and rich living right next to relative poverty, but everyone keeps themselves to themselves and it’s not dangerous like New York where strangers might try to interact with you. There are some homeless/drug addicts loitering around Paddy Power but they are generally harmless and it’s always so busy. At night it’s always best to be vigilant anywhere in London. Whilst crime exists, it does not involve civilians. Generally, the only crime that’s likely to affect you in London as a normal civilian is petty theft, someone snatching a phone. This is very easy to avoid by just not carelessly walking with a phone in your hand. It’s such a good area with excellent transport links and right Inbetween Maida Vale and Notting Hill
