We stayed in Jason's apartment from Saturday to Wednesday and had a perfect time. Everything worked as described but we were simply amazed by some of the things we want to mention specifically:
1) our host was totally helpful and communicated clearly with us before our stay.
2) the already quite flexible check in times were handled even more flexible as Jason offered us to come in earlier than we thought was possible and our quite early checkout on Wednesday was no problem at all! Top!
3) The Appartement was way more spacious (for two) than we had expected and very clean and comfy as well!
4) the ad mentions loudness during the night - however we found the windows did a perfect noise reduction job when closed. at least in the bedroom we heardno noise at all!
5) The location of the place is simply perfect for sight seeing, pub nights and there are a bunch of great dining opportunities only a few footsteps away.
6) Some small benefits include: wifi was fast and steady, shower is spacious and has powerful water pressure, the high livingroom window floods the room with beatifull sunlight, the bed is comfy and warm and had some nice tartan - style blankets.
So, in short: a perfect place to stay in Edinburgh!
