my sister and I stayed at Matthew's 10 days and really enjoyed our time there. the house is lovely, clean and inviting- so is the room, although the toilet a bit small.
Matthew was great and helped us around, advised us which places we can see, how to get here and there and generally was very nice and made us feel welcome.
his house is very close the tube station on the northern line- which was great!
I'd go again.
