Denise is a very warm and welcoming host, and the house and room has everything you could possibly need while traveling. The bed is terribly comfortable, so you might find it hard to get up in the morning ;)
The area is calm, quiet and feels very safe, even at night; the busstop to and from central London is literally a 2-minute walk away.
Golders Green with all its shops and restaurant is only a short walk away as well as beautiful Golders Hill Park which is definitely worth a visit.
I really enjoyed my stay at Denise's home - highly recommend!
