We chose Kevin's apartment as it seemed very clean and roomy. It was everything that we expected and a great value for the price. Kevin is a very honest host and delivers on the advertisement.
Another thing that actually shocked us was his willingness to help us out with out check in. We arrived really early in the morning and there were guests checking out, so the apartment was not ready. He went out of his way and took 6 pieces of luggage from us from the Greenwich Station and left them to the flat for us, so we could go on light with our day to London.
Greenwich is also a great location, though we found ourselves drawn to the city and did not get to explore a whole lot. Transportation was very easy to figure out with no waits via a bus/tube. Just down the street there is a restaurant called EatTurkish, we were also in shock with how authentic the food there was. Check it out, if you are interested!
