Lovely little apartment that myself and partner stayed in for a few days. Very clean and great location for Edinburgh City Centre.
The only tweaks id make is, having tv channels for a few hours relaxing at the apartment (but there is Netflix and channel apps - i just prefer normal TV) and a carton of milk so I can make a cup of tea after a long journey.
Other than that, its a great hidden gem in a fantastic city. Highly recommended.
