Location and flat is good. However, owner should provide clear instructions about how things work in the flat. We arrived at 9pm and flat was warm. In the middle of the night the heater went off and we could not turn it back on. After a freezing night (15deg) at 5am we found the thermostat controller and set it at 22 deg to try to warm it up. After 3 hours it was still 18deg. I called the owner and he said he set an auto timer for the heater to turn off at 11pm (?!?). He came to check and found a top window slightly opened (we did NOT open this window). He said that was why the heater wasn't working. After another 1.5hour it was still 19deg. I texted and in the owners's words - "Temperature is now at 18 deg, which is ok for me but maybe not for someone who isn't used to Scottish winters." (?!?) I asked that he come & check, or we'll want to move. He reset it and finally it warmed up at 1:30pm. It was a waste of our day in Edinburgh. Owner wasn't apologetic about the situation at all.
