Good location, minutes walk to Haymarket station for train links or tram to princess street. Also not far to walk either to the centre 20/30 mins depending on speed. Great location for attending Murrayfield, we went and walked back in no time, you could also get tram to Haymarket and walk up from there.
The apartment was really clean and tidy, certainly had everything we needed and all 3 double rooms are spacious and comfy.
Wouldn’t hesitate in stopping there again if visiting Edinburgh.
