Although I never saw Mr.David during my holiday, he was great host. Detailed information was given by him, questions were answered kindly by him.
The flat is located at centre of beautiful street. It is quite tough to go up to the fifth floor, you'll have absolutely perfect view both in your dining room and the lounge. Hot water, central thermo were easy to use.
A lot of markets, restaurants, bus stops, train stations are nearby. I enjoyed very much in Edinburgh with the house of David.
