Lily's apartment is ideally located to go sight-seeing in London: Borough Market is a 10 minute walk from her place; Saint Paul's Cathedral, the Tate Modern and Shakespeare's Globe just 20 minutes on foot. One day we even walked all the way to Regent Street from there (it took us more than an hour, but if you like walking that is nothing, and you pass a lot of interesting sights).
The apartment itself is comfortable and in a quiet neighbourhood, within walking distance of two supermarkets, tube station and Bermondsey Street with its pubs and restaurants.
