I stayed two weeks in Daniel´s apartment. He is a respectfull and nice host and his apartment is clean and tidy. I think staying in his apartment is a great option for those who plan to stay in London for a few days.
There was only one issue that was disappointing: Because of a sudden and unexpected change in my flights, while I was staying in his apartment I had to ask Daniel to leave two days earlier than planned, and accept my request of giving me the money I paid for those two days back. We respectfully discussed the issue, and he returned approximately 40% of the money I had paid him for those days.
To be fair, he had the right to not give me anything back, as the Airbnb policy favours the hosts (which I guess it make sense, otherwise the guests could change plans all the time, leaving the hosts with their accomodations empty), but due to the difficult circunstances that the world is facing right now I was expecting more flexibility from him.
However, taking that small issue out of the equation, I had a great time there, and I do recommend it.
