Sevdal and her husband are very hospitable, I felt really welcomed. The room they rent out is in the basement of their house. The heating was fully on as November in London can get chilly (and it did). I had my own bathroom, restroom and a kitchenette with tea, coffee, milk, cereals and other little items. The wifi worked seamlessly. The room was cozy and I found the bed to be really comfy, I slept really well there.
I spent my days mostly outside, but Sevdal always came to say hi when she heard me come in. I really loved the personal touch.
I'd recommend Sevdal's place to anyone looking for a nice place to stay at a low cost.
Btw. there's no doorbell, so you need to use the metal knocker :)
