This place, while situated in the literal depths of the old town along “cow gate”, is handily placed to access The Royal Mile and then either up the hill to Edinburgh Castle, or down the hill through Canon Gate towards the Palace of Holyroodhouse. Another five to ten minutes walk (depending on your pace) and you’ll be at Waverly Station and nearer the ‘new town’ and Princes St.
You will need to walk up old and fairly steep cobblestoned streets/lanes to get up to South Bridge - which is not uncommon in the old town.
The apartment felt like a home with a large living/lounge space, kitchen and three bedrooms/two bathrooms - plenty of space for this family of two adults and two teenagers. The floor/floorboards are probably ready for a revamp as there were several loose boards and a few exposed edges (hidden well by strategically-placed rugs).
It is excellent value-for-money considering its location to the Royal Mile, with the only warning being that it is part of an old town building that stretches from the apartment on South Niddry St (actually a closed lane way) up to shops and restaurants that open out on South Bridge that is actually above you - meaning that between about 7:30 to 10:30pmish each night there is noise from (presumably) wait-staff in the restaurant above as they walk (run? gallop?) between the kitchen and the tables. It was mildly annoying, but would only really impact you if you had very young children.
The vibe of the laneway (and Niddry St which brings you down from the Royal Mile) isn’t “family”, but we did not encounter any issues.
Plenty of food and beverage options within easy walking distance.
