Great place to stay! Willesden Junction is just a few minutes walk away, so you can easily get to the centre with the Bakerloo line. There's also a nice little centre nearby with a supermarket and an amazing coffee spot (Dark & Light Coffee).
I got a different room than was advertised on Airbnb, but this one was great nonetheless. I would have liked to have a chair so I could do some work behind the desk and maybe a bin to throw some of my stuff away, but those are just some small details.
Roman also has the cutest cat ever (Casper), who will definitely keep you company if you keep your door open (which I thought was amazing!).
