London advice please


32+1 with my first, and my husband and I are moving to London for ~2 years after baby is born (for work).

Any advice is appreciated, particularly:

1) What are the child care options like in London? How much does it cost?

2) Where should we live? (I will work in Soho and my husband in Victoria.)

3) What will a 3 bedroom cost? A 2 bedroom?

4) Do flats typically have dish washing machines? Washer and dryers?

5) Are we crazy?
