I simply can't recommend Tony's flat enough!!! My 3 girlfriends and I have come to Edinburgh multiple times and always stay in an Airbnb on or near the Royal Mile - Tony's place was hands down our best experience. He was lovely to communicate with, check in was a breeze, and he not only provided suggestions on things to see and places to go (broken down by neighborhood) but he also provided discount codes on tours. We didn't utilize these since we know our way around and already had a plan in place, but this would be amazing for others!
The flat itself was perfect. A GREAT location right off of Victoria Street and the Grassmarket. It was incredibly spacious and, as 4 women traveling together, having two bathrooms was wonderful. We all also had what was hands down the best shower any of us have had in the UK (haha). There is no need to turn on a water heater and the water pressure was consistent. I know this may sound silly, but coming from NYC this is something we all really appreciated. And lastly, all of the amenities were very nice. Stylish decorating, comfortable couch, smart TV with Netflix, two sets of keys provided, etc. We will definitely be staying in this flat again when we come back to Edinburgh!
