It's beyond my understanding how this place had so many positive reviews.
I stayed there with my 70 yo father and my stepmother.
Firstly, the lift was broken, which meant we had to carry our heavy luggage for a total of 6 flights of stairs! Fair enough that this is not the owner's fault; however, the least Toby could do was to offer some help with the bags.
Secondly, the dirt was appalling: the bedroom cupboard shelves were absolutely filthy with dust; the kitchenette floor was sticky; the furniture was old and tired; the sofas were stained; the mattress cover for the sofa-bed had a blood stain!
Also, we arrived in London on a particularly warm week, and there were no fans available in the flat.
Finally, there were no instructions upon check-in about how the water heating system worked - although there was a "users manual" for the flat which included the guests' duties as well as some complex instructions about the heating system. I found it ironic that so many things were expected of us, and yet nothing was offered in return from the host. Our first showers were with cold water, until I've managed to understand and sort out the water heating. However, the shower only trickled a tiny bit of water anyway, which made it really challenging to wash our heads - we had to basically stand on were the bath tap was, with our backs touching the wall.
I have messaged Toby several times during our stay to complain about all the above issues and also to ask for help with carrying my father and stepmother's luggage down when they left; unfortunately, he said there was nothing he could do!
Summarising, I would recommend to stay away from this place, unless you're fit, young and don't really mind dirt or not having a shower!
The only positive thing about the place is the location - which is probably why he can get away with charging £141 per night!
