The location is amazing but that's where it ends in the pros list. On the cons list I'll stick to the most egregious or it won't fit here!
This is possibly the worst furnished flat I've ever entered, think Argos value line after being used by careless people for years. It was dirty... very very dirty and we were glad there was an old Hoover there (just mind you don't electrocute yourself on the frayed wires, you have been warned).
The flat has two showers but the boiler can only run one at a time, yes, I did find out in the worst possible way being sprayed with ice cold water while rinsing my hair and someone put the other shower on. Did I mentioned the showers enclosure is minuscule? If you are even slightly claustrophobic stay clear! Oh, it's also rather grimy so flip-flops are advised.
All in all I've learned that London is a crazy place where £150 a night gets you a awful little flat in a nice location.
