I retired recently and enjoy having guests to stay in my comfortable home in Highgate.
On the first floor of my detached house is the spacious quiet single guest room which is south-facing and has lovely light. You will have exclusive use of your own private bathroom and light use of the kitchen if you wish.
I am lucky enough to live in an excellent location just next to Waterlow Park, a short walk from the world-famous Hampstead Heath and alongside Highgate High Street which has plenty of good pubs and restaurants, and a small general supermarket and delicatessen merely metres from my front door.
