I spent 2 weeks in Jamie's apartment on a business trip. The apartment is very nice, new, equipped with everything that can be used if necessary. It is located in a beautiful residential area of the city, from which you can easily reach the center on foot or by public transport. Haymarket train station and the airport bus stop are just a 10 minute walk away.
The apartment is very comfortable, quiet and offers a relaxing environment: it was very important for me to enjoy such a space after busy working days.
The wi-fi has excellent performance even for those who have to work.
Close to the modern art gallery and on the Water of Leith walkway (a very pleasant cycle / pedestrian path that I recommend) and not far from excellent pubs and restaurants.
From the living room window you have a very suggestive view, in any weather.
Jamie was very kind and absolutely clear in providing all the necessary information at the right time: I didn't need to ask for anything.
Whether you are in Edinburgh on holiday or on business, for a few days or a few weeks, this apartment is really great.
