We had a great weekend in London. The major problem with the flat was that there were no blinds / curtains on and of the windows and have asked for some money back for the inconvenience.
I've emailed them via airbnb and directly and haven't received a reply yet
As it appears that we were the first people in the flat I've sent them some helpful comments - no lights in the stairs up to the flat, no instructions for TV or boiler, we had to buy a bath mat and toilet brush and no shampoo as advertised - but again have heard nothing back
So although we had a great weekend their lack of response has taken some of the shine off our stay
