This is a great little flat. It is very central (~ 5 minutes away from Waverley station, maybe 10-15 minutes to the Royal Mile). It's perfect for a short jaunt to Edinburgh for a weekend of seeing the sights,
Sofia couldn't be more helpful. She's as accommodating as can be when it comes to dropping off bags, which is very handy so close to the station. There's a selection of guides, maps and menus to help you plan your visit. There's also breakfast and tea and coffee provided.
The room is nice and comfortable (I think I stayed in the smaller of two, but it was still spacious enough). There are two bathrooms, so I never had to wait to use it, There are even spare toiletries in the bathroom for anything you might have forgotten.
