We stayed for four nights at Boyd's Entry and found the stay perfect for our needs (couple traveling with 11-month old). Stuart and his wife provided a baby cot and high chair, and also have gone to great detail to provide items that other airbnbs do not (eg house manual to familiarize on fire exits, brochures and discounts available to their guests). It is excellent value for money, having a separate upstairs bedroom and bathroom from the living and kitchen area so it is spacious for staying and literally steps from the royal mile. There is occasional street noise that you can hear from the bedroom but that's pretty normal for the city (or bring a noise app). The kitchen is properly equipped and well stocked, and traveling with a small baby we found it convenient to get takeaway often and enjoy a sit down meal.
We appreciated how close the flat was to Arthur's seat and had a lovely hike, and found the location great for popping out all day or coming back intermittently without feeling you were losing travel time. Stuart and his wife are attentive and available easily for communication. We highly recommend this location, especially to those traveling with small kids!
