Harrow-on-the-hill is fancy, if a little odd. Harrow itself is just a bit of a dump I’m afraid. Harrow on the hill tube serves Harrow well, with fast (a relative term) metropolitan line services into baker st and beyond and children trains into Marylebone. Just as well as that’s about the only reason you’d consider living here. A wander around the shopping area feels you leaving pretty depressed but essential if you’re considering making this place your home.
