Bloomsbury is artistic and intellectual - this lovely neighbourhood is home to many of London's major universities. It has always been a centre for arts, education and medicine. Aside from living in university halls, if you can find a room in the area you will be incredibly close to not just universities, but to places like Oxford Street and to the rest of central London. Pretty and historic, Bloomsbury is a perfect place to live in London. On sunny days, hundreds of people from nearby universities will fill the gardens and parks.
As usual, prices for rooms in a central neighbourhood like this will be high. Most rooms are in small high-rise buildings or in old, and very pretty, Victorian and Georgian houses.
Bloomsbury is a huge educational hub, you can walk to any of these universities: SOAS, University College London, City University, Birkbeck College, RADA, The London School of Hygiene and Tropical Medicine and a mass of other smaller colleges and campuses for foreign institutions. You can also easily reach universities like LSE or The University of Westminster on the tube.
