The house is just as shown in the pictures, located in a very quite neighbourhood.
David is a very friendly and generous host. He made us feel like we were home.
He was keen to go out of his way to make sure everything was perfect for us: he recommended us places to visit in Edinburgh (and music worth listening to), explained us the public transport to make sure we were safe at night, and even prepared us breakfast the next morning.
I definitely recommend him, it was the best place we could have found in Edinburgh.
