Susan was great, and patient with us as first-time airbnb users. She was ready to meet us on time, and showed us around the apartment. The location was great. We walked everywhere (most things were within 20 min walk). The view of the castle was perfect, I just wish we were there during a fireworks display!
The flat was also appropriate for our 5-month old that we brought along. The bedroom was big enough to fit his travel cot (with lots of room left to spare!). There are a lot of traffic noises, as it is a busy street, but this didn't bother us sleeping.
The kitchen was well equipped, and allowed us to prepare a couple meals.
It was a great way to see Edinburgh!
