As others have said, great location for the Old Town and beyond. Although wise to note that with this central location comes city noise, particularly on the weekends, including within the building (other residents using the entry doors and communal stairwell).
Facilities in the flat were as per the description and the couple of small issues we had (broken kettle, need for extra blankets) were resolved very quickly. Overall, excellently-located and has what you need as a base from which to explore Edinburgh.
