Ollie's place is nice and has everything you need including a nice bath and comfy bed which is very important to have after a long day of walking around in Edinburgh.
The flat is quite central, only 9 min from Haymarket bus/tram station. We took the City Link 100 from the Airport to Haymarket and found the flat easily. You can either walk to town if you want to explore or can take the bus as the stops are a few min from the flat. Restaurants and a couple supermarkets are also nearby. I thought this place was good value and will stay again if we visit Edinburgh one more time.
