The flat is clean, check-in/out is easy.
Location is convenient and close to the station. The area can be a bit rough but that's part of the experience in London. Stay alert when you walk on the street (keep your phone in your bag etc) and you shouldn't have to worry too much.
The host Iki and Sania are friendly. Have several lovely conversation with both of them.
Although I would say the communication can be improved as in most occasions it felt very last minute. Don't think it would happen if you are short-term guest.
Also have a small issue with toiletry. As on the website it said the price includes toiletry, I didn't expected to be asked to buy toilet paper. The host said because I was considered as long-term guest so he didn't have to keep buying toilet paper. I went on airbnb forum for host and found the discussion regarding this topic. It seems like even within hosts there are different opinions. I would suggest the host to put a disclaimer/statement on the description saying that he won't provide toiletry for long-term guests to prevent confusion in the future.
Another thing regarding communication is that for the last two weeks of my stay the host moved his friend in another room as he was away. I didn't have an issue with the fact that he wanted to rent out the other room but it was more about how it was done and the reply I got from the host. He texted me 3 hours before his friend arrived at the flat, and when I raised concerned of living with a total stranger to me he told me I should considered myself lucky as I paid for one room but had the whole flat to myself. I don't appreciate this way of communication as a) I didn't ask for the whole flat, I paid for the room I'd be happy to have just the room and b) I think it's normal for a woman to feel concerned about living with a stranger man, yet his reply showed no understanding of that but just wanted me to accept that his friend is moving in.
Again, I would like to emphasise that it's about how it happened and the response I got, hence I only give 3 stars for communication. Everything else is great!
