Staying with Steve was great! We arrived very late (around 2am) at Goodmayes station but Steve was very nice and picked us up there.
The room was very cozy and bright with a comfy bed and the neighbourhood was really quiet (kind of nice after a long day in London city). In the mornings we ate fresh baked bread and could use and eat everything we needed in the kitchen.
A short 15 minute walk takes you to the nearest station and from there you can take the TfL Rail to Liverpool St station in about 20 minutes.
I would definitely recommend staying with Steve!
