A couple friends and I stayed at Steve and Karen's place for three nights on a girls' trip to Edinburgh and had a wonderful time. The space is very large and bright and is in a great location . We loved being able to explore the surrounding area!
The one downside was that the boiler stopped working on our last night so we weren't able to shower before checking out. Steve and Karen responded quickly and did the best they could given the timing but it was a bit inconvenient for us.
Other than that though we had a wonderful time and would highly recommend this place - definitely take a walk to Dean's Village nearby!
