I have a very comfortable flat available from the beginning of August near West Hampstead. It's only 10 min on the tube to Oxford / Bond Street, close to the tube, shops and bars. It's available for either short or long term rent and price can be negotiated depending on the length.
The flat is very comfortable, quiet and has everything in it. It's on a leafy street with excellent transport links (tube, overground and trains are a walk away - you can easily get to the Centre, Hampstead Heath, Canary Wharf, Liverpool Station, Richmond and all the airports.)
Contact me if interested and I will send you more information.
