Lori's room is tucked away in a really quiet part of Dalston, offering a rare bit of London serenity. There's a modern bathroom with a good shower, a comfortable bed, and lots of privacy and independence from the main house.
Some reviews mentioned the trainline, but I don't think you should let it put you off. The line hosts the London Overground (aka the Ginger Line) with trains running roughly 6am-11pm at frequencies between 5 mins - 20 mins, but the sound made by the trains is much smoother and calmer than that of a road vehicle - it's a purring cat, not a yappy dog.
Think of the noise as similar to being in a flat by a road with one car passing by every 10 minutes or so. As central London flats go, it's way more peaceful than most.
I hope to stay again next time I'm in Dalston.
