Chris was very responsive. The flat is in a great location from the train station, and is in and exciting part of the city centre. The flat was very clean and comfortable, and had all the essentials. The only thing to be aware of is that the square blew can be rather loud at night, but it is no problem with some ear plugs. I would recommend this place to anyone staying in Zurich, as this is an expensive city and this place is great bang for your buck!
