The apartment is lovely and very well located. The communication with host was easy and he was very attentive.
There were some important issues though that I must mention: the toilet would only flush once every 6/7 hours. This is could be a bigger issue if you are in a larger group. Also, the eco-friendly shower deregulates quite often becoming extremely cold or hot for no reason.
If these problems were fixed I would highly recommend the apartment to anyone traveling to Scotland :)
