We had a very enjoyable stay in Edinburgh. The apartment is perfectly located - it is a very close, short walk to the main business district but is also very quiet.
The apartment is as advertised. It is a quite large and spacious apartment over two levels with four very large bedrooms and two bathrooms, which makes it great value if you are looking to accommodate a lot of people. There is a spacious lounge room which comfortably set seven of us in a very conversational setting.
Isla was an excellent host and was very responsive and helpful, especially with bag storage on the last day. The apartment was very easy to access and vacate. Overall an excellent experience.
