A good sized property in the west of the city. Plenty of buses to Princes Street (7 services I found, there might be more) plus another that ran to the airport and one or two that avoided Princes Street and went into Old Town directly (as well as others that went to Princes Street and Old Town) . By Bus west end of Princes Street shouldn't be more than 25 minutes away after leaving the flat; if you prefer to walk, it's about 40 minutes (less if you walk fast).
The flat has what you need and there are three supermarkets about 5 minutes walk away with a number of restaurants, pubs, etc nearby.
Hosts very communicative and friendly, very quick to sort any problems out
