Abigail is a very competent and caring hostess. Her flat is situated in Stockbridge, which is sometimes attributed to be a bit arty-farty, in reality is is a wonderful neighbourhood and an excellent start to explore Scotland and the Scots. You will meet real people in real pubs and shops (watch out for uncle Arthur in the Stockbridge Tap); the centre of the New Town is only 15 minutes away by foot, the pubs at Grassmarket a bit further.
The Blue Room is spacious enought for two and very often you'll have the flat to yourself, as Abigail is a very busy person. You should, however, like cats: Whisky and Mac are lovely but everywhere.
