Lovely appartement and very helpful host! If you walk to the city center (takes about 25 minutes, depending on where you want to go) you'll find very cute and good coffee shops and restaurants in the neighborhood.
We just had a wonderful stay in Edinburgh! However, be aware that during August the Fringe festival takes place and the population nearly doubles, also the Edinburgh Tattoo as well as another Festival were taking place, so you will definitely not get bored and if you don't like crowds, you have a wonderful appartement to relax ;) !
