I spent four nights here with my wife and two children. We had a great stay and would gladly stay there again. Some things to help you decide:
1. You are a ten minute walk from either Tulse Hill or Streatham Hill train stations, and five minutes from a bus stop that will take you to Brixton tube station. Trains and buses leave all the time. It took us an hour to get to Kew Gardens via Streatham Hill/Clapham Junction/Richmond, 90 minutes to Heathrow via Green Park, and 40 minutes to Central London via Brixton. We also took the bus all the way from London Eye. The CityMapper app was our friend there.
2. There is a Co-Op "local" grocery store at either train station. You can buy there all you need, when you get off the train. Also there is an Iceland grocery store by Brixton station if you are coming by bus.
3. By the Streatham Hill station is an Indian take-away called Delhi Bites. The guy who runs it is very friendly and takes great pride in his food. We "took away" every night.
4. The listing says two bedrooms but one of them is tiny and filled to the brim with baby stuff. So consider it a one-bedroom with a king bed and a sofa bed.
5. We especially loved the kitchen and garden. It is like in the pictures.
6. Nicki was responsive when we had questions, as was her neighbor Joe, who helped us check in.
