Valentina is the most incredible host you can wish for. I felt welcome and at home in her flat from the moment I arrived -- in fact, before I'd even arrived, as her communication beforehand was so reassuring.
Her flat is clean, cozy and wonderfully located to get to pretty much anywhere in Edinburgh with ease; there is a bus stop less than a minute away, and Haymarket station is a 5-minute walk.
Overall, a top-notch experience. I highly, highly recommend staying with her!
