I found this room to be exceptional value, as the room itself is spacious and comfortable with a great working desk and a sofa. The divider by the bed makes great use of the space too as giving it a sense of being both cosy and spacious.
I found that everything worked well, and the shower was good. Worth noting that the property and therefore the bathroom is shared; so some co-ordination of shower-times may be needed with other residents in the morning.
I marked the location as slightly lower simply because of transport links. The area itself, Battersea is lovely; I used to live here myself and it's so nice having the park and some nice pubs and restaurants in the area. But this side of Battersea park does mean that to get to most parts of London, you're going to need a bus before you can get onto a tube; which can mean longer than expected travel-times.
I found the host responsive and accommodating; and the check-in process was smooth and friendly. Overall definitely recommended.
