Best location you can get in Edinburgh, at the heart of the city centre. Airport bus drops you off 5 minutes away. The apartment itself was well cleaned, with convenient features such as dishwasher, washing machine and easy to use heating that warms the room straight away. The kitchen has all you need for a few days. The staff we met were really welcoming and polite.
Just two notes that might be helpful for future guests, the bed might be slightly small for someone tall, also bring an hdmi cable with you as the tv's are a bit old and don't support chromecast or smart functions.
