The best thing is the location, it’s close to the train station, walking distance to the castle and lots of cafes, bars and restaurants in royal mille.
The landlord is very nice and helpful with prompt responses, the apartment is clean and prepared well, it has everything you need and it’s spacious with nice decor.
The location also brings its drawback which is the noise cos the apartment is just right beside the street, you can hear cars and bars, which doesn’t suit us cos I traveled with young kids, and the building, stairs and apartment are quite old looking. However would definitely recommend if you are traveling to Edinburgh for night life and for its convenience.
