The Royal Mile Apartment is superbly located for your trip to Edinburgh. Just a few minutes walk from the Castle, to the West and Holyrood Palace, to the East. There are loads of attractions nearby - we visited the National gallery and Museum on the Mound and saw the "Castle of lights" at night- spectacular!
The apartment was beautifully presented, very clean and every need was covered. The kitchen was well equipped, with all the implements you would be likely to use, or need (we cooked every day that we were there) and everything was straightforward to use (including a washer/drier).
We arrived on the week before Christmas and had a Xmas tree and dec's up to welcome us in - Little touches make such a difference. The rooms here are warm and well equipped with the usual tv/dvd/sat combo and games/cards - if you're in the mood - and the bed(s) are "super-comfy" (easy to over-sleep here!). For the middle of a City, we noticed how quiet the location was - it's down a small side street, off the Royal Mile, but there was very little traffic. A Big plus.
Overall then , a clean, comfortable, in-expensive and well equipped option for any stay in Edinburgh.
