The flat was as described, a clean and cosy studio for one/a couple.
I stayed for one night so it was fit for purpose (albeit I read an earlier review thankfully to be prepared that there is only a bath and not a shower/hose).
Need not worry about being cold as the flat can get very warm - I had to turn the dial down all the way at one point :)
It is situated in a peaceful suburban style area so the stay is quiet and out of the way of main roads, and actually has more of a residential feel with a couple of local greasy spoons around. The stay is only a short bus from Elephant & Castle tube, and short walk to the nearest cafe - but that's not super effort!
I would just say the price was quite high for one person staying one night - however it was the cheapest stay I could find at short notice as my prior 2 airbnbs got cancelled (my assumption due to the ability to hike prices for the Fury v Chisora boxing which was happening the night of my stay).
