Charlie's place is in a beautiful leafy part of Edinburgh, about 15 minutes walk from Leith, 25 minutes from the center of Edinburgh, and close to a big Tesco and bus routes into the center. He's a gracious host and a great person to chat to.
The only real negative I have is that there weren't many pots and pans, which made cooking for myself difficult, but Charlie offered to cook most nights which was always very good food, and breakfast was on the table every morning.
Overall I had a great month staying with Charlie and would definitely stay again.
