Kentish Town is on the Northern Line. From Heathrow:
1. If you're feeling rich, take the Heathrow Express to Paddington, get on a circle or Hammersmith line to Kings Cross (Eastbound) and then a Northbound Northern line to Kentish Town (destination High Barnet or Mill Hill East)
I estimate about 1 hour for this
2. From Heathrow, take the Picadilly Line to Leicester Square (or Kings Cross) then change for the Northern Line as above.
About 1.5 hours for this.
