One of the properties we visited when we were looking for a house was the old boulangerie in Preuilly, which is opposite the Maison Renaissance.
We loved the 11th century cellar and small section of colombage (half-timbered) balcony, but the lack of garden was a problem. As was the one semi-underground room of 110m² - we had no idea how we would use such a space.
Another problem was the communal staircase. The house has no stairs of it's own, but shares a very worn spiral stone staircase with the semi-derilect building next door. The stones were so worn that they would requre boxing in using wood.
The photo really doesn't do the stairs justice - we are sure theys were more worn than this, so maybe I just couldn't get the most worn stairs into a sensible photo.
