We absolutely loved our stay in John's Airbnb! The location is absolutely perfect if you are looking to stay in Old Town. Yes, the area around the apartment can get loud, but that is what we expected with that area. Most, if not all of the noise ends around midnight, even on the weekend. There are a lot of restaurants and coffee shops within 10 minutes walking distance of the apartment. If you are looking to avoid the crowds on the Royal Mile, I highly recommend getting out between 7:00 and 8:00am. The area is empty since most places don't open until 9:00am.
The apartment was very easy to locate and was VERY clean. The bed was comfy and the shower was great. I think that is mainly what everyone is looking for!
