We spent a couple of nights in town during the festival. Photos are representative of the nice apartment located in the old city next to the Scottish Parliament. Clean sheets, modern bathrooms, kitchen with all equipment (dishwasher, microwave, etc ..).
We have not met Abbey, but we were helped by Jacop, the concierge at the hotel next to the apartment building, which welcomed us with great courtesy and availability, helping us with luggage.
The apartment is located at the end of the old town, a short walk from the Royal Mile.
highly recommended
