Lansbury Heritage Hotel is fantastic. It's starting to look a little bit run down in the narrow and small lobby, but the rooms are fantastic. Great water pressure in the shower, space in the minibar for your own stuff, great beds and lovely pillows, great lighting system that allows you to control everything from the bed.
It's difficult to get here with lots of luggage, you'll likely want to get the DLR to Poplar even if you travel with the Elizabeth Line.
I'd happily return!
