I strongly suggest to choose this amazing airbnb.
I chose the single room 'cause I travelled alone, which is spacious with a super comfortable bed (believe me if I say spacious 'cause I always bring half house with me!), the bathroom is just the next door. You can have a delightful view of the garden from the bedroom. Everything is impeccably clean. The kitchen is spacious and if you're lucky enough to find nice weather, you must have breakfast or tea in the garden at least once!
You can't help but to fall in love with the dog! (and the two cats are lovely too)
Above all, Katherine is nice, helpful that let you feel at home.
Parsons Green is just few minutes of walk, you can find a Coop market, couple of bars and a pub near: it's a very quiet neighborough and you can (silently) walk alone even in the middle of the night. There's a useful bus stop just opposite the park that can bring you even near Soho or directly to Kensington Olympia (for various festival or exibition).
TIP: Just use the "Citymapper" app to move easily all across London, super easy from here.
I want to thank again Katherine for the amazing stay.
