I am not the greatest fan of London (or cities in general) but Biljana's place made the experience of visiting pleasant from the moment that we got through the door. It's cosy, tasteful, clean, welcoming, warm and, above all, surprisingly quiet. The bedroom is comfortable and the view is a delight: at night, the lights on clusters of far-off office buildings on the horizon - and you can see a surprisingly long way - almost look as if they've been CGI'd in.
Travel is pretty straight-forward. We used buses from Archway a lot as that was a useful hub from which to catch tubes into town, but Finsbury Park is equally convenient (although cunning plans to go there to get the Piccadilly Line to Heathrow were thwarted since the Piccadilly Line was shut. Check in advance if there might be engineering works that could scupper your carefully-made plans!). It's also a good location from which to walk, if the inclination takes you. There's a green 'corridor' not far away (that leads to Highgate tube station), Crouch End and its foodie places are walkable and so is Hampstead Heath if you want a good stroll (although it will take you over half an hour to get there but that's probably no burden on a quiet, sunny Sunday morning).
Two points to note. The road outside has parking restrictions (unsurprisingly) but some don't apply at week-ends. However, the whole area lies within the Ultra-Low Emission Zone, so most cars will have to pay £12.50 on any day that they're driven there, something that non-Londoners may not realise. This ULEZ starts as soon as you cross within the bounds of the North Circular (A406) although that road itself is not included in the Zone.
Secondly, when you go out, make a note of landmarks to identify which is the right front door as it's easy to confuse them even in the daylight, and walking up steps to each one to check the tiny house number does make one feel that one is acting a little suspiciously!
A lovely place to stay and I would be happy to stay there again.
