We live in a small block of flats and have our own balcony which has pots etc and a sand pit. We have a communal garden which is all grass which is about 70m by 70m. Its fantastic for the kids and well and truly hidden. No-one ever realises its there. So we have a "park" for the kids to play in and our own little oasis of colour. Not bad for the middle of a city.
So what, if any, sort of garden do you have?
