The flat looks nice, a better photo of the bedroom would be useful, it just looks small and cramped, with no storage or room to walk around, more information may help, such as parking, walk to the station (miles mean nothing to me and sound a long way, where as if it was say 15 minutes walk, it doesn't feel so bad)
A photo of the communal area may help (as some flats I viewed many years ago had horrible communal areas, I.e. Cramped and full of peoples pushchairs etc)
Otherwise I think it is a case of waiting for the right people and their is someone for every property. Good luck
