This is a really outstanding place if you're looking for somewhere to stay in Edinburgh. It's a reasonable walking distance to the city centre and many of the major tourist attractions (about half an hour), it's very close to a major street with plenty of restaurants, take-aways, and other shops while still being quiet, and it's just a lovely place to stay.
In general it was clean, warm, and cozy. Gabriella has filled it with art and helpful books and maps. There's a sizeable living room as well as the bedroom, kitchen, and bathroom. Both the kitchen and bathroom are very well-equipped - we didn't do any serious cooking but we absolutely could have. Gabriella even left us some local beer for our first evening!
I really can't recommend it enough and we will absolutely check its availability if we're ever back in Edinburgh.
