The flat is as advertised on the listing. We were greeted by Diana and she gave us a complete overview of the flat and explained where the tourist attractions were. The flat is child friendly as there were many board games and even a fold up playpen available.
The location of this flat is only 5 minutes walking distance from Holyrood Palace and a 10 minute walk away to start the climb of Arthur's Seat. The Royal Mile runs from the palace to the castle. There is also a grocery store that is about a 5 minute walk away.
If you are wanting to catch a taxi you just need to walk about 2 blocks and then wait for one to pass by. The longest we had to wait for a taxi was 10 minutes.
The only downside we found was that the mattresses for the beds were too firm for what we are accustomed to. However, for others this may be fine.
If we were to visit Edinburgh again, we would have no problem staying at this apartment.
