Dave was available all the time on his phone, he answered all our questions (you book with TravelNest but the lenders are pillowstops). We could even arrive earlier than check-in, which was very convenient. As Dave was not available, he explained us how to do the self check-in, which was very easy and clear.
The flat is spacious, very nice with wooden floor. Perfectly matching the pictures.
The location is perfect, very central, a lot of activities at 10 minuts walk (including the castle and camera obscura).
The stair case to the flat is not as nice as the flat itself, but it's not an issue.
I would book this flat again if I go back to Edimburg.
