Staying chez Kirsten has been a great experience. Gorgeous apartment combining classic and modern items and with all commodities: short walking distance to reach the old Edinburgh (10-12 minutes where you will see nice antique shops), a very close supermarket and the bus stop is just opposite Kirsten’s apartment. Line number 27 will drop you in the Royal Mile/Castle in very few minutes. Botanic Garden is also in the area.
Kirsten is a great host: kind, outgoing, very helpful... She recommended places to visit, got for us a program for the Fringe festival and asked regularly if anything was needed.
Highly recommended option to spend some days in the city! :-)
