I am happy to recommend Pat's place to stay once visiting London. Me and my friend came for a yoga workshop and needed an affordable and cosy place to stay. The flat was very clean and the room was warm. The street very quite but there are trains on the other side so if you are sensitive just grab the earplugs.
We could use a kitchen and prepare our breakfast or a dinner which was very helpful.
There is a wonderful park close so we were passing by it every day. You will find a sweet coffee place within a minute from the apartment. Camden is market is also very close. Pat is a very warm and helpful person. You will definitely feel like at home in her place.
