The good: Very lovely hospitable people. Ideal location (close to the tube and stores), clean room with much space, nice beds, clean bathroom/shower.
The 'bad': water pressure in the shower was on the low side, but then again I've yet to find a good shower in London, so basically you will get this everywhere else as well. the breakfast was a bit minimal, but given the very low rate for the room it's more than fair and they do offer to cook you a proper english breakfast for only 5 pounds.
So overall if your looking for a place to stay in Northfields, its definately the place to go to!!
