We have spent 3 months in Susan's annexe because I had a short-term position in South Kensington. The communication with Susan is easy and as soon as you need something, she helps you very quickly. The flat is well-equipped and comfortable. It is sufficient for a short-term period. It is located in a cosy and safe area with a lot of trees and beautiful houses (it does not look like the area near South Croydon railway station). You can reach the railway station (zone 6) in 12-15 min and there are regular train to London Victoria and London Bridge. I recommend this accomodation.
