The flat was very well located, just around the corner from Pimlico tube stop and a 15 minute walk from Victoria station. It was spotlessly clean and Louise responded quickly to any questions. Overall, very happy with the experience!
Be aware that, depending upon which flat you are in, it can be a 5 story walk without an elevator. This wasn't a problem for us, but if you have mobility issues or a lot of luggage it can be a lot. If this was communicated in the ad, I missed it.
