Great location, the furthest we had to walk was 30mins to reach Holyrood palace and park, but most places we wanted to visit were less than 15 mins away. There are a handful of supermarkets and restaurants nearby which were all listed in a file in the flat. Nice cosy flat, enough space for two and it is true to the photographs online. Unfortunately there were construction works opposite but for most of the day we were out exploring and when we were in it wasn't too loud, so didn't affect us too much.
Would recommend staying here (if you can manage the stairs!).
