If you're looking for a place to stay in Edinburgh - I highly recommend this apartment! It's located at the bottom of Royal Mile near the palace in Old Town but is a quick walk to just about anything (the city is fun to walk around in so this works out perfect!). A bus stop is also right outside for those who don't want to walk. Owen was quick to respond to messages and provides a list of recommendations.
Overall, it was a great experience, and would definitely stay here again.
One warning: the apartment is located on the third floor so make sure you're able to carry up your luggage about 60 stairs.
