Mark is a friendly and accommodative host! His lovely place is in a very centralised location which is close to the train station, Edinburgh Castle and Arthur's Seat. The room was bright, clean, spotless and had all the basic amenities. We were pleasantly surprised to discover the toilet was equipped with a heated floor which is surely a lifesaver in the cold! A pity we only had a short 1 night's stay, hope to be back again! :)
