the bedroom, kitchen, bathroom and toilets were roomy and clean
Real unpleasantness: potential customers are warned about late-arrival
fees on the site, but with no amount specified; "late arrival" meant
after 6:00, as we learnt later on by email.
Our original flight from Frankfurht was overbooked and the replacement
flight to Berlin was due 4h later: the owner agreed to meet us at 8:00
against 50e cash!
Then, our replacement flight was cancelled (along with all other flights
from Berlin!) due to weather conditions: the owner simply said there'd
be noone to open the door to us, refused to leave the key with anyone,
so we had to find emergency accommodation while on the train to Berlin!
No-amount-specified "Late arrival fees" are mentioned on the site for
sure, but nothing about "nobody there + rooms prepaid + no refund" if
you turn up later (11:00, in our case: not that late!!!)
