Sunny Flat is perfect for a few days away exploring Edinburgh, Stockbridge is lovely with great shops, bars and cafes and I recommend getting an Uber to the city centre.
Positives on the flat are good wifi, good shower and kitchen amenities.
A personal negative for me was feathered bedding which I’m allergic to but worth knowing incase someone else planning to stay there is too, overall good value for money as a base to your stay.
