My family stayed over Christmas, while I live 10min by foot from the apartment. The location is one of the best in Zurich, meaning surrounded by restaurants, public transportation, supermarkets, bars, and at the same time in a residential area. They didn't stay much in the apartment besides sleeping. The beds were comfortable. The building door wasn't closing and the light in the stairway wasn't working. Made the experience unfortunately not the best even though these are not related to the apartment itself. It's important to keep in mind that it's an old building so you can expect to hear neighbors, etc... Filipa was super fast in answering my messages and it was easy to follow the descriptions to do a self-check-in.
