Bring earplugs to this HMO.
You get a door key so there is some privacy.
I did not meet Shoma and was let in by a man who did not introduce himself.
The acommodation is very basic and 15 minutes from the station (not 10).
The place is clean and for what you pay, I'd say it's worth it.
On the other hand, there are babies in the house that cry a lot (like all babies do). You can hear every conversation. It didn't feel like a welcoming stay, I never met the host though I did ask after her.
Overall, I would recommend staying there for 1 night. It got me to Canary Wharf in the morning.
