This is a comparatively safe district of London. You are however still in the city, so be sensible, especially after dark. If you do run into any difficulties, these are the main police stations in the district:
Hampstead Police Station
West Hampstead Police Station
Cope
Royal Free Hospital
One of London's largest and most famous hospitals. Has a full A&E department.
Hampstead and Highgate Express
Very few London districts have their own proper local newspaper as opposed to a free sheet, but it is no surprise that literary Hampstead does. A great source of local news, events and listings. Published each Thursday, and widely available at newsagents and other outlets throughout the district.
Internet outlets
The Internet Cafe
A small internet cafe offering light bites and drinks. Wrong phone number.
Belsize Library
A small public library run by Camden Council which offers free public internet access. The queues are often long though.
Swiss Cottage Library
A public library run by Camden Council which offers free WiFi and a limited number of desktop stations.
Queen's Internet Cafe
A rather quirky place which doubles as an internet cafe and a supplier of hair grooming products! Very friendly and a reliable, fast connection.
