Staying at Ola's place was superb, I'm really glad that I chose to stay at hers for my first month in London. The place is very artsy, clean, and in a very nice neighbourhood. It's decently close, but not too close to tube, overground and rail stations, and Clapham Common is a very nice area to explore. Ola and her husband were the kindest people who helped me a ton in navigating flat hunt, among other London settling-in things. I would totally recommend staying at their place!
