Diego's flat is located roughly 10 minutes away from Kentish Town Station which gives great links into central London.
Everything was very clean upon arrival and he even left a large box of Fox's biscuits in the living room for me which was very thoughtful.
The TV in the living room was great for watching YouTube videos through casting from my phone.
Diego was also super helpful when I wasn't entirely sure where the flat was or how to get unlock the door since it is quite old. For any future travellers: once you've turned the red key to the right, pull the key and door back towards you, then you'll be able to fully rotate it and the door will be unlocked.
The other small note is the train tracks next to the flat (which is mentioned clearly). If you're a light sleeper like myself, I would highly recommend bringing ear plugs as they were pretty much vital to me getting enough sleep.
