What would be your choice?
A South London top third floor newly built property with balcony? With next door neighbours, and neighbours in the opposite building, playing loud mega bass music? (I don't know how they get away with it? It can be hear down and across the street!) 
Or a ground floor newly built property at the back of the same building? Surrounding by other buildings back yards, with no properties attached to its sides, only two family apartments above and a back yard which can easily be hidden from spying eyes?
Two extremes. So hard to reach a decision.
