The apartment is lovely, very well located, closer to Holyrood than the Castle but within walking distance of all attractions. It can be a little noisy with general noise from the street but that's due to the age of the building I guess, didn't bother us too much during our stay. Despite requesting twice, the beds in the main bedroom weren't made up as a double/king and a couple of bulbs didn't work which didn't cause too many problems more niggles. Would still recommend the apartment, just make sure you receive a response if you make any requests to ensure they're delivered.
