Everything has been perfect: great location (but still quiet at night to sleep), clean place, prompt answers to mails and whatsapp.
I cannot think of any issue in the 3 nights we spent there.
Only one remark (that I put after, because it is indeed a detail): the organization manages multiple accomodations, so the check-in was at their central office (as explained to us immediately at the time of reservation), then we could go to the flat, that in any case was only a 4-5 minutes walk and was not really a detour from the train station.
