A little bit of confusion meant that Helen's son was a bit late getting to the flat to let us in, but when he arrived, showed us through and gave plenty of information of both the flat and how to get around. (even though we had previously stayed in Edinburgh) The description was just as listed, but being at Holyrood, the Royal Mile is all uphill from here.
At first we thought the neighbourhood was a bit rough around the edges but always felt safe day & night.
