Locationwise it's going to be incredibly hard to beat: 30 meters away from zone 1 and a tube station right around the corner. At first we were a bit afraid that noise might be a problem because of it, but with the triple glazing: not a worry to be had. The room is nice & spacious, and has a ton of storage - something most rooms will only have sparsely.
Last, but certainly not least: Chris & Leroy were very nice and accommodating from start to finish - one could not hope for better hosts. You really feel right at home from the moment you walk in the door - and isn't that the real reason why most of us use Airbnb.
So I'd wholeheartedly recommend this Airbnb!
Getting a room like this, in this location for this price - it's a steal!
