The location is quiet and calm but it's further out from the city (it takes around 1.5h to get into central London without spending exorbitant prices on the southeastern rail). Nonetheless, if you are interested in exploring Lewisham and Greenwich and the surrounding areas, this place is a viable option.
Gina's place is clean and well-kept and the room is sufficiently large and comfortable. However, this place might not be suitable for people who tend to stay late night outs given that the quiet hours are greatly emphasised, especially given that the home is fairly out from central London.
