I highly recommend Tamsin as an AirBnB host and her place as a place to stay to enjoy Edinburgh.
Although my overall stay was brief (one night) it provided me with everything I needed and was a relaxing and inviting time.
The sea view outside the house is lovely and there were a number of straightforward bus lines for getting into the city itself within 20mins.
The room and bed were just the right size for a solo traveller and everything was safe and secure.
