I had a pretty good stay at Matthew's place. The house is a 8-minute walk from Lewisham Station (zone 2), 6-minute walk to a Lidl supermarket and about 15-minute by bus to Cutty Sark in Greenwich.
We had the top floor (two bedrooms and a bathroom) by ourselves. Furniture is basic but bathroom is pretty recent. Matthew added a fridge and a microwave for us during our stay.
Matthew is pretty quick in his communication. Easy going with typical british sense of humor but very organized. He provided me with detailed information about the neighborhood (even a hand drawn map), transportation in London and activities in the neighborhood. The only thing is that in his recommendation/rule/advice, he asked that the bathroom be cleaned after usage (which we did most of the time) but that felt like a unnecessary burden for us during our vacation.
