Amazing location- really couldn't have been better. The walk from Waverley train station took 5/10 mins and the tram from Princes street to get to the airport (30mins tram ride away) is just 5/10mins walk as well. The castle is literally outside your door.
The space is wonderful and spacious and has some many quirky areas (like a den-like seating cubby hole) and a lovely little balcony looking out over the rooftops.
It is so quiet in the flat, couldn't hear the trains past 10pm ish in the lounge and not at all in the bedrooms.
The kitchen and bathrooms have all the things you'd need, and the bedrooms have lovely comfy bedding- we both slept incredibly well.
The flat, as described, is on the top floor and so if mobility is an issue this is not the place for you however if you can- it really does give you the best views over the city.
Rebeccas tips for the city were so thorough and gave us some great ideas of how to spend our time.- Edinburgh was always a lovely place to visit but I wouldn't want to stay anywhere else now other than Rebeccas apartment.
