Possibly normal for Scotland, but we were taken by surprise by how the heat worked. Only would work 2 hours at a time. So you ended up getting cold in the night, waking up, and turning the heat back on. The Host did offer another blanket for the bed, but for a stay during winter it got cold at night.
The location was very good. Right at the bottom of the Royal Mile. We could walk anywhere in the city in about 20 or 30 minutes, with plenty of sites to see on the way. The apartment was well furnished and sized well for up to 4 people, but there was only two of us.
WiFi worked well. Never felt unsafe in the area.
