My friend and I didn't meet Ola, but her family was very welcoming and helpful. The neighborhood is quiet and feels safe to walk at night or whenever; if you're uncomfortable with that, just stay alert. It got a bit cold for us, but that was fixed with extra blankets. London transit is a bit costly, but we were expecting that. (Also the weekend we went, the easiest train to Victoria was out of service, so that was a bit difficult to work around.) Wifi worked well. All in all, a nice place to stay!
