My son (age 11) and I stayed for 5 nights and the flat/house and neighbourhood exceeded our expectations. The house was exactly like the pictures, and we immediately felt at home. You can tell everything has been refurbished recently and the facilities all work as new (my son especially appreciated the wifi). It was clean and I loved the decor. The bed is super comfortable. The bathroom is very spacious with beautiful lightning from the window and the kitchen/living room had what we needed. My son even said could he move in for good :).
The neighbourhood Stockbridge has a very mellow Sunday casual kind of feel, but has a lot of shops, restaurants and delicatessen shops. We quickly felt welcome in the area. As mentioned it only takes approximately 15-20 minutes to walk to the centre of Edinburgh and 5 min by bus. We contacted Antonia the first night as it was a bit cold in the flat and she immediately responded and gave instructions how to turn on the heater. Generally she answered very quickly every time we contacted her. We absolutely loved our visit and only experienced one issue. Apparently the wall is paper thin in the bedroom to the neighbouring flat. During one of the nights we were "entertained" from 12 to 4 in the morning by the neighbours enjoying some..adult time which kept us awake. It was only one night though, so we would definitely come back and can only recommend it to others.
