This is an excellent apartment, and Irene and Daniel were outstanding hosts. The apartment is exactly as advertised, but even more impressive in person due to the wonderful light, fresh air, and breeze through the apartment when the large windows are open. It is in perfect condition, like new. It was elegantly decorated, with lovely plants, interesting books, plenty of space, and comfortable furniture. The rooftop deck was wonderful for eating or relaxing. The automated hatch for getting onto the roof (including an automated shade for controlling the sunlight) made it easy to get up and down.
The kitchen was very well-equipped not just with cookware, utensils, and dishes, but also several useful food items in the fridge, coffee pods for the espresso machine, tea, milk, some Swiss chocolates, and more. There were also several useful items one doesn't normally expect, like scissors, tape, aluminum foil, etc., making it very easy for an extended stay when sometimes such things come in handy.
Irene was exceptionally organized, being available upon our arrival and providing a full tour of the apartment and all its facilities, and even serving us coffee and lemon-mint water. The 2-in-1 laundry machine was convenient and worked well (the tutorial from Irene was most helpful for being able to operate it!).
Moreover, we had an unexpected health problem arise during our stay (due to catching an illness while traveling), and Irene went out of her way to help us. She went shopping for us, provided all sorts of helpful information, and checked in on us frequently. She made sure we were able to reach her in case we needed any help. She also was very flexible and kind about extending our stay. We feel very lucky to have had such kind and helpful hosts, in such a nice apartment, during this unexpected health issue. In every respect, Irene and Daniel were kind, helpful, informative, and respectful.
The location is excellent: there are multiple nearby shops, bakery, pharmacy, restaurants, markets, and other interesting places. The neighborhood and the building are very quiet; all we could hear most of the time was the chirping of birds. It is very close to ETH Zürich, taking less than 10 minutes walking or by tram to reach the central campus. The closest tram stop is a few minutes away, on Tram Line 10, a direct connection to the airport, making arrival and departure convenient. The tram will also take you directly to/from the main train station and central Zürich.
We have stayed in dozens of AirBnB's over many years, and this is one of the very best experiences we've had, with the best hosts. We would definitely stay here again and recommend it to others.
