Extraordinary! I completely recommend staying at Janet’s place, not only because the apartment is amazingly well cared and cozy but because Janet is the best host possible. She offered to help me out with anything from the very beginning: transport, tips about local traditions and lifestyle, translating german documents and on and on...
For me, staying at Janet’s place has enhanced significantly my stay at Zürich and, for that reason, I honestly encourage you to book this apartment!
