3 bedroom flat to swap in London Bromley-by Bow

hi, I want to move as we need a house for big family. I am living in 3 bedroom flat that is only 5 minutes walk from Bromley-by-Bow tube station on left and 5 minutes walk from DLR Light railway station on right. Bus service is available outside the building block. Surgery is inside the village as this development is called ST.Andrews Village. Saninsbury, Big Tasco is on walking distance as schools and other amanities are around. This development is car free area with no parking and no garden. There are two lifts in this block.
