Many thanks Paul for your suggestions, recommendations and attentions. The apartment is perfect. The location can not be better to spend a few days in Edinburgh 5 minutes from the castle and in full royal mile. There is taxi stand and tourist bus right in front. Paul welcomed us and brought us a few snacks so we could settle in peacefully: milk, juices, biscuits, croasants, etc. The apartment is immaculate. The wifi works perfectly. thank you Paul.
