We really enjoyed staying in Elizabeth's flat for 4 nights - it became a home from home with the 3 well-sized bedrooms providing plenty of room and the large, bright sitting room a great place for breakfast (croissants from Victor Hugo 2 mins away...?) and other meals. The flat is in a pleasant residential area but with easy access to central Edinburgh across The Meadows, and Holyrood Park (with Arthur's Seat).
Parking was easier than I had anticipated - permits are needed for nearby parking but only from Monday morning to Friday early evening so the weekend was no problem; for the weekdays we moved the car to South Lauder Road around 15 minutes walk away through a very pleasant neighbourhood.
Other notes:
easy check-in
lovely furniture and high ceilings
small but well-equipped kitchen (oven, washing machine)
two flights of stairs up to the flat
