Today the building is completely residential. Mahony and Ukolov’s flat, which they’ve lived in since 2009 and found through an ad, is located at the end of the courtyard. From their door, adorned with a tapestry of a waving cat, Ukolov emerges to greet us, along with the first of their three flat mates, Lotte, a longhaired Siberian cat. Minnie, a tabby is just inside. We’ll later meet the white, rounded-face Bonsai, or Bonz as they mostly call him.
