Check-in somewhat problematic: a day before arrival, asked about keys and didn't hear back. Then saw that house manual contained a passcode, for main door and flat door. But when we arrived, after entering with the passcode through the main door and getting to the right floor, none of the apartments had a place to enter a passcode. Used the wifi information to narrow it down to one part of the floor. Sent a message and called host, no answer. In the end happened to find keys under the mat of an apartment, tried them, compared the flat to the pictures and moved in. Two days later, in response to a further enquiry about the location of the washing machine, the host replied to apologize.
