Helen has a clean, quiet flat with en-suite bath (shower). Extremely convenient to walk to everything in central Edinburgh. We walked to everything between Holyrood Palace and Edinburgh Castle. There are a wide variety of very good restaurants within walking distance and the Tesco is within walking range if you need anything.
Parking is available on the street but remember that it's metered during work hours on weekdays. However, the RingGo app on your phone makes managing parking easy and it's really not a big expense if you're going to be parked there all day. You'll want the RingGo app on your phone anyway because it services parking locations all over Scotland.
