4 Old Tolbooth Wynd is a great apartment for two or more people. It is only a short walk fromt the train station, and car parking is available, if you need it. It is just a block off the Royal Mile, and is close to bus stops, ATM, and grocery store.
The apartment itself has everything needed, even a washer. Basic supplies like coffee and tea were provided. The apartment was clean and well lit. I would definitely consider 4 Old Tolbooth Wynd if I'm in Edinburgh again.
