Ailleen's place is perfectly situated in Grassmarket, very close to the old town and easy walking distance from the new town and most attractions in the city. It was super clean with a very warm and cozy atmosphere that made it a really comfortable base from which to explore the city for the weekend. It was a little noisy on Saturday night (I was on the sofa bed in the living room which overlooks the main square) but I had earbuds with me so it was really fine. Overall, a great stay!
