Ryan's flat was really great, I absolutely recommend it to anyone. It is 25-30 minutes walk from the city center, but a lot of bus stop can be found around it. The canal that is 1 minute away is beautiful, and romantic.
The flat (especially the kitchen) has excellent facilities and it was really comfortable, even if the sofa bed could have been more confortable.
If I go back to Edinburgh I will choose Ryan's flat again.
