Maria was very welcoming and helpful. The detached studio was clean, smart and well-appointed, though not adapted for eating in, so one had to eat out every day. Complimentary coffee and snacks were provided. The wifi worked well. Good hiking in nearby Edgewood Park, Huddart County Park and beyond. Convenient access to highway 280, to go north or south, or up over Skyline to the coast at Half-Moon Bay. Emerald Hills is pretty and quiet, but tricky to find your way around the maze of residential streets there - easiest with a satnav, otherwise get a detailed map, arrive while it's still light, and be prepared to drive around quite a bit. Note that 753 is on the right-hand side going up the hill. There's a box with that number in the grassy verge on the opposite side of the road, but do not turn up the drive there - you are liable to be foully abused by the lunatic who lives at the top!
