If you have limited time to visit Edinburgh, I will recommend this apartment. Most attractions, a lot of restaurants and shops are just around the corner from this place. In fact, a museum is directly across the apartment. The square immediately outside the building is also a famous stop for most walking tours in the Old Town and it also draws in a couple of passersby even well into the night. During all the nights of our stay, we would hear music and singing into our rooms but we weren't too bothered as they would eventually die down around 1/2AM.

Apartment was spacious, clean and tidy during our arrival. They welcomed us with a few breakfast things that made our first day comfortable as we just came from the sleeper train. One thing to note is for the house manual to be more updated--we had to figure out what was wrong with the wifi codes, and the TV but eventually got to it after contacting John and Jayne. The steps to the apartment weren't a problem even for my 50+ y.o. parents (only during the start and end of our stay when we had to carry our luggage).

In sum, apartment is recommended because of its location, and value-for-money.
