Great location, just behind Edinburgh Castle, ~10 minutes walk from Edinburgh Waverley train station and the city centre. Nice neighborhood with good pubs and restaurants. Check-in procedure is straightforward, and the descriptions are very clear. Anne is a very responsive host, and the amenities (heating, warm water, WiFi) work very well. The mattress I found very comfortable. The flat itself is in the basement (which makes this a bit dark in late autumn/winter), and there was some drainage/humidity issue when I stayed there in November. Flat faces towards the garden which makes it quiet.
