A really easy way from the airport to the apartment, a 2 minute's walk from the bus stop. We arrived at the restaurant/bar downstairs, Trystan's girlfriend showed us the apartment. The room was big enough, though not very warm. It was freezing in the kitchen, so we didn't use it to cook. The shared bathroom was clean enough although the water from the basin wasn't heated. The location is ideal, just a stumble and a stroll away from the Royal Mile and other sights.
The only minus about the apartment would be the noise at night, not sure if it was coming from the bar downstairs or the bars in the area, but it kept us up alright.
Have to say that the communication with Trystan was perfect, before and during our stay!
