Nice, clean and quiet apartment, located right at the foot of Arthur's Seat, a grass covered hill, remains of an extinct volcano, that seats right in the middle of the lovely Holyrood Park.
If you can manage to reach the top on a clear evening the view at sunset is quite nice (even nicer with a beer).
The flat is also just a 10-min walk from Edinburgh's Old Town - the oldest area of Edinburgh, where you'll find the city’s most important landmarks - and about 20-min walk from the New Town area. I went for a 7.00pm show at the Edinburgh Playhouse and walked there and back with no problem.
There is a nice pub right down Holyrood rd (The Holyrood 9A) and a supermarket (Tesco) right on the other side.
If you have enough time I recommend a visit to Leith, a port area in the norther part of the city.; a 40 min walk from the apartment.
