We very much liked our stay at Dylan's place.
It was not located at the heart of the city centre, but that was completely fine with us as we had the botanical garden across the street. Going to the city centre was perfectly possible by foot and we enjoyed our daily walk doing so.
The apartment itself looked like it was completely renovated, it felt brand new, completely clean and organised. The apartment had all the right vibes, it included a spacious kitchen and a trendy bathroom. Dylan himself was very friendly and helpful and was kind enough to share some tips about how we could pass our time in Edinburgh.
Summarized: we had a great time!
