I went to Edinburgh for a week this spring, and had a fantastic stay with Misia.
The room was large, bright and beautiful, in a very pretty suburban neighborhood, just 15 minutes' bus from the city center. Misia and her husband were both very accommodating, and let me leave my bags with them after arriving earlier than the check-in time. They made sure I had anything I needed and were always really nice.
The breakfast was really good - a large continental breakfast with several kinds of bread as well as meats and cheeses and jams, eggs, pastries, yoghurt and fruit, with tea, coffee and juice.
The buses stop right outside the house and go directly to the city center, making the journey short and easy.
All in all, I had a very lovely stay and would definitely recommend it to anyone traveling to Edinburgh.
