I stayed in The Music Room which had a comfy bed and a separate bathroom with a good shower (a rarity in the UK) and access to a quiet courtyard garden. The house was shared with other ABNB guests upstairs and Christina and Les themselves who are on the top floor. The place has a good kitchen where you can prepare your own meals and gives you separate fridge space. Security and access was fine, though it is about a minimum 10 minute walk to Kings Cross tube and St Pancras Station. I actually was able to walk all the way into central London in about 30 mins, but depends if you prefer walking. I clicked with the hosts as we had things in common and would certainly stay again.
