This flat is uniquely located next to Edinburgh castle. It is authentic and full of character. The beds were clean and quite comfortable. It was well equipped with washing machine/dryer and an adequate kitchen.
However, the bathroom was extremely small and basic and the hot water in the shower was almost dangerous ( boiling hot one second/ freezing cold the next ).
It is also very very difficult to access with suitcases.
If you are looking for something with charm , this flat certainly has that.
If you are looking for something comfortable, there are probably better options.
