It was a trip of 4 nights with children (15, 13, 7 and 3 years old).
When we arrived Diane was very kind and available, she put us in the Scottish atmosphere to start from the beginning a very good trip.
The apartment is easy to find, near a supermarket, very full, and very clean (except a few kitchen utensils). It is located 5 minutes walk from Holyrood Palace. The city center is accessible by bus. We never waited more than 5 minutes a bus to get there. The journey from the airport to the apartment cost us 25 pounds (for 6 persons). If you want to enjoy the nightlife of Edinburgh, maybe it is a little out.
Personally I did not find the mattress very comfortable, I don't know if it's because I do not usually spring mattress or if it's because it is a bit old. However the pillows and duvets are of excellent quality and feel good, it was very nice.

Regarding the apartment if you have children :
- It is generally very practical : lift, microwave, high chair, cot, toy box with a wooden train , board games , books, DVDs, a bathroom, shower room.
- The blinds in the bedrooms and the living room does not completely obscure the light which can be annoying if your child is sleeping in complete darkness (which was our case)
- The high quality doors are held by hinges and a chain. Each time the door is closed , even gently, the chain mechanism generates a very big noise like a " clack " very inconvenient when you want to verify that a child sleeps well or if someone wants to get up while others sleep

Overall we are very happy with our stay and would return again.
