A great apartment in a great location. Just don't follow Google maps to get there.
Edinburgh is very hilly, so following Google maps might mean walking your luggage up about five flights of steps. While the apartment building has a lift, the streets of Edinburgh don't. If coming from the tram or Waverly station, just walk to North Bridge and turn right.
The apartment itself is well equipped, bright, and situated perfectly for exploring the Old Town or walking over to New Town for dinner.
