Clever idea for the balcony’s furniture is to get some of those folding chairs and hang them on a wall so that they save space, and when you need them, you get many extra seats in a moment. Remember to choose them in bright colors to decorate the wall they are hung on.
After furniture and floor covering, comes the most interesting part; plants of course, what else could it be? You won’t feel how lively & refreshing your balcony is without adding plants & flowers. Feel free to add them everywhere; they will never look too much.
