Hello everyone!

Can anyone give me some advise about this :
I will be moving from the French Riviera to London beginning of January.
As I ve bought new frigde, tv, bed, washing machine, ... about 6 month ago when I moved to the French Riviera, I was thinking of selling everything and buying new when I will arrive in London and get a flat :
I can see that most of the flat to rent are already furnished, I am correct or is it as well possible to get unfurnished places and is it cheaper usually to get an unfurnished place?
Thanks for your time

Kevind
