Kasia's flat is immaculate (ly clean) and very welcoming. Good wifi, and there are universal chargers by the bed, so really no need to bring adapters! She left very clear instructions for checking in (early, thnx by the way!) and the flat is located just a few minutes' walk from Crossharbour LDR & bus station. Greenwich, Canary Wharf & the O2 are easy to get to.
The room itself is not very big (big enough!), but the bed was VERY comfortable, which is basically all I need when I travel by myself 😊.
I'll definitely book again when I'm in the area.
