Hackney City Farm, London

We have been to London quite a few times this year and have always been mega busy with either pre-booked activities or other plans I have made! The last time we went we were there for 4 days and 3 nights meaning we had quite a lot of time to fill. London can be very expensive though with meals out for all of that time as well as the accommodation and travel costs both to get there and on the tube. Recently, I have been trying to find more and more free or super cheap things to do in London
