Tracey's place is absolutely great. The bed is big and comfy, very clean and spacious. You have your own bathroom which adds extra points. There's two tube stations near by and lots of buses going to the city center as well. The neighbourhood is very safe too, perfect for a solo traveler woman.
Tracey was super friendly from the beggining. She received me very with a smile on her face and gave me a house tour (their daughters are super nice too!). I'd stay here again :)
