I truly enjoyed my stay at Pamella's place. I decided to stay in Greenwich because I visited a friend there, but since Pamella's place was a 4 minute walk from the train station, from which you are at London Bridge station in 8 minutes, it would also be ideal for people who focus on the Westminster-area.
The place was clean, Pamella was very friendly and helpful. I mainly kept to myself and I felt this was respected. Kitchen and bathroom have all the utilities you need and the bed was comfortable. Because the proximity to the station, light sleepers could consider ear plugs. The lounge area was temporarily unavailable but I didn't miss it. If you are looking for a comfortable 'base camp' for a stay in London, with a friendly host and in lovely Greenwich, look no further.
