I got to the flat before the host did, eventhough he booked a time for us to meet- if i were to be late he would have given me a penalty. I somehow managed to enter the flat and the building without him being around. (Other airbnb guest helped me in and told me that the communication with the host and his assistences are not coordinated).
The toilet flush didnt work in the evenings/night- beware. The front doornobe comes out when you push open. Hot water didnt work on the last day- couldnt take a shower before leaving.
Its a cheap price- you might be getting what your paying for.
I booked a slitly more expensive room for my next trip(Next month) to London.
