Located in a quiet neighborhood that's really near most of the attractions - so that part is a major plus. Check in was really easy and straightforward. Living room and bedrooms were spacious (though kitchen a little small). Susie made sure all bedsheets were fresh and clean - which was important for us. Main toilet is renovated to feel nice and clean - that's awesome too... and Susie was responsive throughout our stay.
The only main issue we had was we couldn't get the temperature to be warmer and we all felt kinda cold (17-19 Celsius indoors) throughout our stay (maybe some of you would like it at this temperature).
The other slight issue was that the wooden floors were sort of creaky and walls were thin - so we could actually hear the conversations in the kitchen while we were in our bedroom next door (but it's not a big deal to be honest).
Other than that - we enjoyed our time in Edinburgh!
