Karen's flat is located very conveniently close to many shops and restaurants, plus the bus stop is super close with lots of bus connections to the city centre. The building is very quiet and felt safe and the self-check-in and out process is really easy. The flat itself is very well equipped with anything you might need, we found it well cleaned and my parents thought the bed is quite comfortable. Overall a great experience, would highly recommend for a short or long visit to Edinburgh!
