Totally recommend Margareta's room. My parents stayed there over a long weekend and had a great time. The house is spacious, clean, has everything you need and is in a quiet location.
The house is well situated to get to Hackbridge station, it's only about 15 minutes walking and it's a nice walk too.
Special mention to Margareta who made everything so simple for my parents, she's the kindest and most flexible host ever.
