We had a great time in Edinburgh at Chiara's place (4 days). The location is wonderful : close (but not TOO close) to the historical center, just outside a very nice park, in a lively area full of nice shops and restaurants. The place itself is fully equipped and decorated with a lot of taste.
Finally, Chiara is a wonderful host. You can feel she cares a lot about her guests getting the most of their stay, which can make all the difference between a good and a great time in that lovely city of Edinburgh.
