It's a very nice small flat and very convenient for our purposes. Everything was impeccably clean and kitchen well equipped for cooking breakfast.
Communication with Mario was flawless, unfortunately we didn't meet him in person, but it really wasn't necessary, since the self check-in process was very smooth.
The location may seem a bit remote on the map, but it really wasn't, we managed to walk to sights in all three directions: centre, Leith and Arthur's seat.
Unfortunately, we didn't use the dvd player, because Mario's dvd collection lacked the essentials: Braveheart and Trainspotting :-)
