Mercedes has cleverly created a charming, tastefully- decorated flat out of limited space. For a couple it's perfect. Very comfy mattress, walk in shower, and downstairs to a small kitchen and sitting area. All contemporary and clean. Lovely part of the old town, with narrow streets and plenty of atmosphere.
Ideally don't have a car (parking was hard to find) and wear ear plugs if you don't want to be woken by cars/horse and carriages outside your window.
