This flat was absolutely perfectly located for touristing. Being just beneath the castle and at the foot of Grassmarket, it was super convenient to get to all of the major sights in Old Town. My mum and I were pleasantly surprised by how spacious the flat was and how comfortable the beds were. The kitchen was very modern and fully equipped and there was plenty of space for two people to work together in it. Catriona was a fantastic host! She sent clear and detailed instructions that made check in and check out a breeze and was very responsive during our entire stay. I would give her 6 stars if I could!
