We stayed in Mario's gorgeous apartment for 3 nights for my partner's 30th. When we arrived, Mario met us and showed us where everything was, gave us some handy information about the local area, and made us feel very welcome!
The apartment itself was lovely, very clean, very conveniently located, and just the right size for two people. We'd highly recommend both the flat, and Mario as a host, if you're looking for a brilliant time in Edinburgh.
