The location is perfect. Blocks from the royal mile, Edinburgh castle, and old town. Plenty of space to spread out and great amenities. Washer/dryer and dishwasher came in handy. Communication was impeccable. Lots of details pre, during, and post use.
Areas for improvement: no wifi which would have been nice. The showers in both bathrooms were literally held together with duct tape. They worked, but not a nice aesthetic. The process to pick up/drop off keys is strange - over a 1/2 mile trek with luggage was a bit cumbersome.
