The room in Anna's apartment was very comfy, tidy and nice.
It was really calm and near to bus stop and tube station. Even at night I always felt safe. It's next to a school, but only shortly before nine it gets a bit noisy.
Bermondsey is a quiet area with many family homes.
It's not far from London bridge station and tower bridge. A short stroll to several nice pubs and supermarkets. A bit longer to the more fancy places around town hall and London Bridge.
Anna herself is a very nice and helpful person. Easy to chat with.
I can recommend staying in her apartment for everyone.
Only if you have troubles with stairs it's not a good choice. Narrow stairs to get to the apartment and inside one more to the room and bathroom.
