If you are looking for the best place in Edimburgh you won't regret choosing this one; the location is perfect, only two minutes walk from the Castle. The views from the room were stunning, watching Scott Monument from the bed is worthy. The appartment is cozy, everything neat and clean and newly refurbished.
The host was so welcoming and kind. Our flight had a delay and though he was waiting for us and had even bought us something for breakfast. If I were you I would definetely give it a try.
