Charlotte was a lovely host. She very kindly let us check in early, since we had a morning flight. The apartment is in a great location, within walking distance to a lot of restaurants, pubs, attractions and just down the street from a supermarket.
The bathroom is updated, though the rest of the apartment is a bit worn. What you can't see from the photos is an abandoned building between this apartment and the castle (though the view is still amazing). Overall, this makes a great home base for exploring Edinburgh.
