The apartment is very close to London Bridge tube station, some shops, restaurants and pubs. At the same time it was quiet, which I was glad about. The room was clean and one room-mate (it is an appartement with three students living there) answered me any questions I had. Everything was fine.
The fact that my arrival time changed (the trains were late at that date because of floodings on the way) was no problem at all and I was received and guided very kindly.
