Ozlem's apartment is great for a simple, comfortable base for your London stay. It was very clean and the bed was comfortable. The views of the park and the London skyline were great, especially at sunset. The underground is a 15-20min walk but it's easy enough to access. Close to restaurants and pubs and plenty of nice parks around as well. Ozlem was really responsive and easy to get in touch with.
One thing to note is that you can hear people walking around in the apartment above so it may not be the best for super light sleepers.
