Canary Wharf is a major financial district in London and contains many of the UK's tallest building. Being business district, it is very busy in the day and somewhat deserted and quiet in the evenings and weekends.
However, there is some shopping around that area and a very good selection of pubs and restaurants, which makes it still a nice place to stay. Not a bad place at all to stay if you visit London.
For me, the best part about staying at Canary Wharf was that I could walk to work. This really makes a difference because it meant I could go in to work easily at an early hour. But it also meant I ended up starting my day at around 7am in the office every day! I even got in one day at around 640am!
