It was only a short stay, but I had a great time at Johanna.
The house is easy to locate, and Edinburgh is a very well-organized city. All information was relevant, and the house was easy to find; buses 30 and 14 run frequently, taking you downtown in 10 minutes. If you have more time, you can also walk down.
YOU GONA LOVE IT.
I wholeheartedly recommend it.
