People often overuse the 5* rating. Really, 5* should be reserved for places like Sophias. The flat was really well layed out and has everything you need, and things you didnt know you needed (but now you do), there was loads of nice touches, and it was super clean.
I stayed for 5 weeks during covid, but for those staying in normal times: the flat is in a great location for exploring many of londons sites, like Tower bridge, the tower of london, bank, tate modern, Westminster, and more.
