Everything's as advertised. Dave is an experienced host, check-in was so easy and even he wasn't around. He is also a great guy, he helped me a lot with the bus ticket and bringing my luggage down. Keep in mind, the apartment is on the 3rd floor and there's no lift.
Room has everything you need and even more - umbrella considering Scottish weather was a pleasant bonus. Dave provides a really good breakfast as well.
The location is not right in a middle of the city center but quiet and has a nice park. Still if it's a good weather and you're a good walker there's no problem to get to popular sightseeings. It took me about 1 hour to get to Edinburgh Castle by walking. If you plan to hike Arthur's seat and visit Holyrood Palace it's a great place to choose. Nearby (about 7 minutes from the place) you'll find a shopping center - TK Maxx, M&S and Sainsberry's for some food and essentials.
