Lovey old mansion next to the Greenwich park. When I say next, I mean literally next to it. From the window you can see the park and the Greenwich Observatory. Greenwich is easy to reach by boat and the DLR train.
This place made our stay in London even more enjoyable and we will definitely be back. Trish and Tim are very helpful but also respectful of your own privacy and space. Greenwich is great if you come from Dover by car, easy to get to and easy to get out again :)
