My sister and I stayed for 6 nights. The apartment is charming. The castle view out the living room windows never ceased to amaze. Bed was very comfortable and kitchen and bathroom small but functional and fine for our needs. A few lightbulbs burnt out in bathroom and bedroom didn't help the poor lighting for putting on make-up, but we made do. Grassmarket nightlife noise was not a problem, especially as we kept back bedroom door shut to keep out the light at night. Very sorry we never made it to Mary's Milk Bar right next door due to their limited hours and our schedule. Highly recommend Surgeon's Hall Museum Blood & Guts tour, climbing Scott Monument, Arthur's Seat (if you're fit), Calton Hill, Holyrood House, Royal Yacht, Dean Village, Auld Hundred steak pie, Real Mary King's Close tour, St. Giles Cathedral interior, Devil's Advocate dinner, Stirling Castle.
