I arrived on a really cold day in the UK and was worried that I would be cold but the room and rest of the apartment were nice and warm. The house is only 5 minutes on the bus from Central Brixton on a quiet, pretty street (all of the neighbours were friendly and helpful).
I didn't use the rest of the apartment as I was out most of the time but the bed in the room had new pillows and was very comfortable. There was always plenty of hot water to take a shower in the shared bathroom too.
The host is very friendly and responds quickly to messages. One point to note: there are stairs outside the house and inside the apartment so try to pack light.
This is in a great area of London to enjoy a peaceful stay whilst being close to Brixton and Central London on public transport too.
