I had a great time in London. It was my first time using airbnb and the experience was pleasant. The room was very cozy, the bed comfortable and hot water, which was crucial in this cold weather. The room was also warm, heating works perfectly. You could make your own food if you like, however being in London you should definitely try out some restaurants.
Unfortunately I couldn't meet Catia as she was working, but her husband was kind and welcoming. I can't thank him enough for making my stay memorable.
I really hope to be back soon:)
