This apartment is brilliant! It is in the best location, right in the middle of it all. The train station is about a 10 minute walk away. We could walk everywhere, the only tourist place we had to taxi to was HMY Britannia, but it was only a short 15 minutes away in the taxi and cost no more than £10. If you didn't want to taxi, you can catch the bus or walk. The area is lovely, felt very safe and clean, there is a lot of cafes/restaurants around as well as tourists shops, supermarkets etc... It's really easy to find as it's right next to the Fudge shop which was bad and good :) I really couldn't recommend this place more! William was a great host, very welcoming and helpful.
Whilst in Edinburgh, I would definitely recommend walking up Arthur's seat if you get the chance, the views are amazing of Edinburgh! Well worth the visit and would love to go back sometime! :)
