We stayed at Barry's place for 5 days. The location of the house is just perfect. All the major tourist attractions like Royal Mile, Edinbugrh Castle, St. Giles Cathedral are just at walking distance (3-5 minutes away). There is bus stop nearby as well (in case you want to visit other places in the city).
Barry is an amazing host. He was very quick to respond to our concerns/requests.
We will definitely stay at this place whenever we visit Edinburgh next time !
