Mario is very responsive and accommodating host.
The goods: Apartment is just as nice as photo. Large windows with sunlight coming thru and trees outside. We're driving, hence distance to town is not a concern. Parking is free on road; brilliant. Nearby has a big shopping area with tesco, M&S, £shop etc (meadows bank? Forgot the name already :P), very handy to get groceries and feel the local life.
Things to note: it is a walk up on 2nd floor in a relatively old building (in context to hk, not sure in Edinburgh) with a little dark staircases, so be prepared if you have big/ many suitcases. Entrance to building has garbage collection boxes parked (not sure its location change or how it works, but the 3days we were there it was there), which might be a little unpleasant, also make the entrance a little easy to be missed.
Good experience overall and good value.
