The flat is perfect for a couple but even a family with one or two kids can spend some time comfortably. We were with two kids and one slept on the couch and the other on the air bed and that was perfectly fine for us. The flex itself on three levels and is a unique experience on its own. Both we and the kids really enjoyed it. . The terrace with the view over the river and the city is truly phenomenal. We had nice weather on all three days of our stay and spent a lot of time on the roof. The location is ideal for tourists as many things of interest are within walking distance. We did not meet Alex as she was traveling but she reacted promptly to all our inquiries and the checking and checkout went very smoothly. We would not hesitate to book again for our next visit to Zürich.
