Just spent 3 nights at Sonia and Chris' apartment, and we were very happy! The quality of the apartment is at a high level, e.g. the hotel quality bed linen was very lovely, and the kitchen crockery was all in sets!
We used the sofa bed which was actually very comfortable, and we're fussy!
Being a basement flat, the 2nd bedroom was at the back of the building and therefore had no windows, as per the kitchen and bathroom. However, extractor fans cleared any cooking smells or shower steam!
The apartment is right around the corner from cafes, supermarkets, restaurants in Stockbridge (you must go to Nok's Kitchen)! And the area was very upmarket and felt very safe! It's a simple walk up to Princes Street, although walking home was much easier as downhill!!
We needed to contact the host for something, and their response was very quick.
Would definitely consider staying here again!
