the apartment was beautiful, clean and very cosy. Even if it's very close to the center of Edinburgh it's very quiet. A bus stop is only a 5 minute walk away and the buses take you 24 hours wherever you want.
It takes a 15 minutes walk to the center, which is very easy and nice to go. Waverley station, where you can take trains to nearly every corner to the U.K. is only a 20 minute walk.
Mario was a great host, answered all of our questions, gave us Tipps for our stay and was there whenever we needed him :)
I always would recommend this apartment and would always come back :)
