My opinion about this flat is not certain.
For example, the location is very nice and you can see the tube station right from your window (Northern line). It takes you 15 min to get to Westminster and 25 to get to the Tower (both by tube). Very good and cheap car park (15 pounds for overnight stay) is situated in 3 min (on foot). But the street is so busy, that you can't sleep in silence and darkness. We used ear plugs and it was really helpful.
The flat is quite small, but has two separate rooms. It was very important for us as we travelled with children.
The kitchen is very small as well, but it has everything you need: microwave oven, toaster, electric kettle and even washing machine.
The flat is clean but the bath became clogged each time you use it. We used a plunger but it didn't help a lot.
One more moment to mention is really steep and long stairs (the flat is on the top floor). There is no lift.
