The location of Simon's place is hard to beat, overlooking St. Katharine's Dock and just across the street from an excellent supermarket, Waitrose. You can walk to Tower Bridge in 6 minutes and the Tower Hill tube station in 10 minutes.
It also has a roomy, and well-functioning kitchen, good internet and a terrace with a small table and two chairs which overlooks the water. The skyline view is beautiful (just like in the photos) with the Shard and Tower Bridge on the horizon.
Two things to be aware of: 1) The bedroom windows of the flat overlook a public sidewalk which is used as an informal gathering place for people to sit and chat. If you have your windows open, you will hear what such people are saying in both the bedroom and livingroom. For some people this won't be a problem, but for others it might. 2) The unit is a bit old and could use a little sprucing up, perhaps fresh paint and new flooring. I would consider these minor drawbacks.
All-in, it's a good space in a great city.
