This apartment is outstanding. The view of Edinburgh Castle from the living room window is exactly as shown in the listing. The location makes Princes Street, the Royal Mile, and Edinburgh nite life easily walkable. We spent a week expecting to use public transportation but only needed a taxi back to the airport. There is a grocery store one block away, and pastry shops in the same block.
Importantly, Taiba, the owner, was prompt in responding to our communications. We had an issue with the newly installed hot water heater and she responded in minutes. She had an engineer there in about an hour.
She also gave us suggestions on pubs, places of interest, and walks to take.
Only concern for sum is that it is at the top of three flights of stairs. We four are all 70+ and it was no problem. But if stairs are an issue for you, be careful.
