The master bedroom is generous in size, and the two additional bedrooms, one of which features built-in bookshelves, are ideal for a nursery, study, library, or guest room. The full windowed bathroom has been updated, as well, and the apartment also has an LG combo washer-dryer. Original pine floors lend rustic charm and warmth to the space.
