STAY AWAY from this appartment and CHECK MY GUEST, the agency running it ("Co-Host"). We lost 400 Euro because of them, and they are not willing to refund.
The appartment has an electronic lock with a code. Well before departure time, we wanted to get our baggege out of the appartment, but the lock did not work any more. It just didn't move. Our train to Switzerland would depart two hours later, we had already booked the tickets for 4 persons. We called CHECK MY GUEST, but they did not help us for over 2 hours! We talked to numerous call center agents, just telling us "someone is on the way". Their office is just about 40 minutes away, but it took 130 minutes to solve the problem (the electronic look did not work any more, it needed a normal key we didn't have). CHECK MY GUEST wasn't even able to solve the problem, it was the cleaning woman who came by chance at that time. After all that, the agency told as that they did our best. They refuse to pay the tickets for the train we missed. STAY AWAY!
