We (4 adults - one couple and two friends) stayed at the apartment for 8 nights over new years and had a great time. As other reviewers have noted: a very stylish apartment (exactly like the pictures) in a very interesting part of London - so far we never stayed on this side of the river. Borough Market is just steps away and so are a lot of good chain restaurants (Wagamamas, Nandos, Pain Quotidien, Zizzies etc) and a lot of attractions Brough Market, Globe, Oxo, Tate Modern, St. Pauls etc.).
Getting to the city center is easy - the RV1 Bus from Hop Exchange connects directly to Covent Gardens and the tube is available at London Bridge with Monument and Bank so close by it is easier to walk there than to change lines.
Although we did not meet in person, the communication with Fernando was fast and efficient - he answered all our (many) questions in the shortest time.
For us four the apartment was great - and a good value. We highly recommend it and would stay there again anytime.
