The Airbnb is exactly as seen on the listing, a large room with a beautiful bathroom on the same landing and a ridiculously comfortable mattress.
There is a folder full of information in the room with recommended restaurants [The Royal Oak is a fantastic pub within 5 minutes walk] and other relevant facts. The tube station is a short walk away but as he mentioned there is a long flight of steps just shy of reaching it, so given that I was lugging around heavy bags I took the bus instead, which drops you around 100m from the door.
As a single female traveler I felt very safe both walking around the area and in the Airbnb. If anyone is worried about the mention of a dog in other reviews, rest assured that Ed is an extremely well behaved dog who while being very friendly is well trained and is kept on an entirely different landing than guests, so he is not a bother at all. He was a definite plus point for me!
My flight home was abruptly cancelled and Colin was really accommodating in allowing me to extend my stay at the very last minute! so kind. Highly recommended, would stay again.
