Fiona's flat is in a great location, only 20 minutes walk from Canongate and even less coming back ( it's mostlydown hill!). There are plenty of buses in and out of town either from Easter Road or just around the corner. You can get buses to the old town area or Princes St, Haymarket and beyond.
The room is huge and very quite, lots of storage space . There is a good selection of shops in the area, cafes, pubs, takeaways, supermarkets etc many of which are open quite late.
