This is a lived-in house and very much feels like someone's home. I was greeted by a friend of the owner who showed me my room, gave me my own key and left me to my own devices thereafter (he was available to ask if I had any concerns though).
The location is well connected for the bus directly into the North side of Zone (you'll be at King's Cross in 15 mins and the centre of London in another 5-7 mins). The nearest tube station (Finsbury Park) was about 15-20 mins away but again provides a quick journey into the centre of the capital.
If you want somewhere that is a good price for a comfortable bed, quiet and left alone for the most part you won't go wrong with staying here.
