I had a lovely time at Helen’s place and felt right at home. It’s a bit of a ride to central London (about an hour via bus then train) but the trip is easy and bus stop is very close by. Affordable café and grocery store down the road too. My room was clean and comfortable, and I had no troubles at all with the shared bathroom and kitchen. Highly, highly recommend if you’re looking for a very affordable place to stay without sacrificing comfort.
