We stayed at Callum's place for 2 nights in October. Callum is very friendly and communicated well before we arrived and during our stay. The flat was perfect for a weekend get away. It was a 20 minute walk to the Waverley train station and there are lots of local bars and cafes. Callum was helpful in recommending some of these.
We would definitely recommend Callum for anyone planning a trip to Edinburgh.
