I regularly stay in London but this was my first time to Highgate and will definitely be back. Tim's place was easy to find from Highgate station (although I later found out Archway is even closer!) and being just a few minutes walk from the village high street.
Check-in was a breeze. The room is lovely and big, with a comfortable bed, lights, table, chair... the wifi works perfectly (btw, mention out to AirBnb... nice one for the in-app 'connect to wifi' thing , genius :-)
Tim is a great host - very welcoming and sociable. Great stay, lovely room, wonderful apartment and fab location. Bravo!
