Helen's place is lovely, I'd thoroughly recommend it for anyone wanting to spend a few nights in Edinburgh. It's entirely self-contained so you have your own entrance and shower room, and it's in a beautiful part of the city. The city centre is a 10-15min (uphill) walk away, with loads of great bars/restaurants en route. If you come by car, there's street parking right outside but you will pay for the convenience (£2 per hour and you can use Ringo). For breakfast I'd recommend the Water of Leith café at the south end of the street - very friendly with great food and smoothies.
