Loved our stay at Helen's place. The location was ideal - a good distance from the city, but still easy and convenient to get to the city center by an easy walk or a quick bus ride. The area is quiet, but has enough shops and restaurants for convenience. It's also in a quiet area, which is much appreciated after long days out in the city center.
Helen (and family) are also incredibly nice and hospitable - helping us with everything we needed. We loved our stay at their place and would stay there again next time we are in Edinburgh.
