I don't really have a favourite room, I love the whole place! It's a tiny, 100 year old Victorian terrace with a great yard, considering the smallness of the house itself. Oh, & plenty of outdoor decking.
I love it because it's the first place I've actually owned, all by myself. It is such a relief to feel at home again after leaving my previous home of almost 16 years ... what a wrench that was!
I guess if I had to pick a favourite place it would be out the back, on the verandah ... My favourite place to reflect, dream & plan.
