We had a great stay at Jason's apartment. Its in the perfect location for visiting Edinburgh. It's clean and has everything in it you need. It's also spacious but you may struggle with 8 in the kitchen. We had 6 and it was fine. There are lots of stairs but they are quite shallow so not as bad as you may think. It's walkable to all the sights, shops, bars and restaurants some being just round the corner so a great place to stay to explore Edinburgh.
