The Check-In office at the central station is hard to find.
We were there on time, meaning when the check-in is supposed to cost nothing. We had to wait until it was our turn and the Check-In took very very long and in the end we had to pay the 30 Euro fee for checking-in late. This is not fair.
In the apartment there was no hot water, we had to spend roughly 1 hour on the phone with someone from italianway and still we couldnt fix the problem. He told us we get a 100% refund for this night which we did not get. And although we agreed on calling the next morning at 9 a.m. sharp he and italianway did only come back at us at around 10:20 a.m.
Conclusion: not a pleasant stay and the opposite of relaxing
