I stayed at Christina's place for 5 nights during a business trip. She was very welcoming and friendly, adviced me on things to do in London. We had lovely chats and even went to the local pub one night. At the same time, she was very consideratere of my privacy.
Christina's flat is a lovely and individually decorated place in the heart of London. It is indeed only a short tube ride to the center of London - and the bus connections are good too. Next to the room I rented, she invited me to use all facilities in the flat. The room itself is very cosy. You'll have all you need - bed, small table, chair, clothes rail, shelf, and a mirror. It has two big windows which let in a lot of light during the day and you can use the blinds if you want to sleep in.
I can only recommend to stay at Christina's place. She is a terrific host and the flat + room are very comfortable. I hope to be back soon!
