My wife and I loved staying here! The space was perfectly located. 5 minute walk to trains, buses and airport tram, 10-15 minute walk to Old Town, 15-20 minute walk to Lawn Market and countless restaurants, shops, monuments, statues and attractions along the way. The apartment was very clean and orderly. It was very nicely decorated and had all the amenities we needed. Since there was no TV, we sat in the living room and listened to the radio, read and recounted our trip.
My only additional comment would be that if you are a light sleeper, like I am, I would suggest packing ear plugs if you're sleeping closest to Rose St. Bar and restaurant goers can make some noise as they're leaving for the night. Ear plugs downed out any noise.
I will definitely recommend the apartment to friends and family members traveling to Edinburgh.
