It's not in the old city center Chur. But it can be reached by a direct bus going both way and will pass Chur Bahnhof. The room is quite compact. But they have this great hair dryer in the bathroom. Thumbs up! IBIS rooms are not spacious as always. The room without air-con is no problem for us because we stayed during July. The night wind cools down the room quickly.
The only down side I want to say is that they don't have a microwave for guest to use if they buy microwave dinner.
There is a pet shop at the back of Ibis. A SPAR mart next to it. But on Sundays, all shops are closed. I am not sure about the gas station mini store next to IBIS. I hope it will stay open 7/24.
