It is located in an excellent location where is two minutes walk to Edinburgh Castle. And ten minutes to Princes street and train station.
Rooms are clean. Various kitchen equipments can be easily found. In general, this is not a bad choice for you when travel to Edinburgh
But, for those travel with elderly people, it is not convenient for you to reach 5the floor. During winter, heater in living room doesn't work efficiently. I still felt cold at night. If there is a back up e-heater prepared in the room that would be nice.
