A crazy number of stairs. Impossible to heat or cool. Everything is inconvenient. Floor cabinets are tiny. Top shelves are almost inaccessible.
He just flat out says that it's hard to live in the thing.
"The total area of the apartment is around 100 square metres (1,100 sq ft), but around a quarter of the space is unusable because of the walls that are under the angled ceilings."
So it's quite small.
