Initially we had a small problem checking in as we couldn't find the lockbox, but I called and was given a more detailed explanation of its location. I would suggest adding a picture of the lock box with the check in instructions. Once we had the keys though, everything was fine. Flat was clean and tidy, and has everything you need. Location is great, as its walkable to the royal mile, grass market etc. Holyrood palace is only 5 to 10 mins walk away. Only other suggestion would be to fit black out blinds, as in the summer you would probably be woken up early by the light coming through the slats of the blinds. I usually bring stick up blinds for this reason when travelling with the kids. Wasn't a problem for this trip though, so just a suggestion really, not a complaint. Check out process was also really simple, and overall we were really happy with our stay.
