The apartment is in a very good position, 4 mins walk to mansion house underground station, and at a walking distance to borough market, the tate modern gallery and saint Paul cathedral. It was clean, and comfortable for 5-6 people, with two bathrooms. John was very precise with the information on the area and on the house.
The only negative thing is that this is not a private house of someone that lives nearby, the girl that welcomes you is very kind and precise, but you don't get the experience of being hosted by British people. It is more like renting a house in estate agency, the timetable for checking in and out are very strict, and there are many rules.
Overall a very pleasant experience, u would recommend it for practicality and efficiency.
