Myself and a friend visited Edinburgh for a few days and stayed at Catherine's apartment and we would definitely return!
It's the a great location, lots of little cafes and shops a stones throw away. The apartment itself was spotless with loads of little touches we appreciated! We especially liked the mini xmas tree :-)
Catherine herself was a great host also, gave us the instructions on how to get the key etc. And left us to our own devices :-)
Thanks again for the great apartment we thoroughly enjoyed it and exploring Edinburgh!
