My friend Katy Regan and I went on our second mini-break recently. Mini-break number one was to Barcelona in the summer of last year, this time we decided to take in Tallinn. In both cities we did hours of walking but Tallinn by comparison is much, much smaller and more compact than Barcelona and easier to navigate around, although I wish I hadn’t insisted on wearing heels all the time – not the best choice of footwear for cobbled streets, stylish but silly.
