I had a wonderful stay!
Thank you Peter and Engin for being great hosts. If I go to Zurich in the future and your place is available, I would love to stay there again!
Peter and Engin are both friendly and thoughtful - if you meet them, they will stop what they're doing to have a friendly chat, give you tips about the city, ask if you need something or offer you more coffee. They always answer the messages very quick.
They also offer services useful for a longer stay - such as putting your name on the mailbox or cheap laundry (for 0.15 chf).
The place itself is really nice as well, and it is perfect for a summer stay. In the neighborhood there is a zoo and a beautiful forest for a walk or a run. There is a tram stop directly next to the building, where you can quickly commute to the city center. There are also 2 shops - Migros and Spar and if you walk 200 meters downhill to Kirche Fluntern - there's also Coop and a bakery.
I have left only 2 days ago and already miss this place. I hope to come back one day and I highly recommend staying with Peter and Enging to anyone planning to visit Zurich!
