Despite the earlier negative review here, we have booked two nights in Ulmenhof via booking.com. What followed was probably the worst service experience I had during the past 10 years and I have traveled in over 80 countries and stayed in all kinds of places.
First of all because my friend had to work late, we missed the check-in (8 PM) and thus we were forced to pay 80% cancellation fees despite not staying there. We asked them if we could at least have a breakfast tomorrow since we are paying 40 EUR for nothing (and they got money for free) and they said no problem. Despite the hotel being fairly big, they don't have any night check-in facilities and wouldn't leave the key at a neighbor or so, they just did not care.
We arrive in the morning - the receptionist and the other person helping us were amazingly unfriendly despite the hotel being almost empty. We almost had to laugh - we just paid 40EUR for nothing and had to put up with them telling us that our handwriting is ineligible and that despite their reassurance that we could have breakfast now they said the breakfast was already finished. After asking them again several times, they brought breakfast upstairs. Guess what, the next day they charged us for this breakfast despite not telling us it would be paid (we just paid 40 EUR for nothing...) Amazing...
We go for breakfast the next morning, the woman is unfriendly as ever, she tells us we should sit in a far away corner, we tell her we already sat down in another place - she says it's not possible (!??!?) because we would have to reserve it. Again, we almost laughed, the restaurant was completely empty... Then she said ok... It was just amazing how unfriendly somebody can be - these people really shouldn't be in a hospitality business.
Then we try to check-out and again trouble, they tried to overcharge us (despite overpaying for breakfast and paying 40EUR for empty room we couldn't use) - come on, do you guys care about your guests at all or are you here to squeeze every last Euro out of them while giving them bad experience? We wanted wifi and guess what, 5 EUR per day, 300 MB limit, come on... You want a safe key, 2.5 EUR per day I have never seen anything this bad before, it is amazing they are still in business, they just don't care about their guests at all, it felt as if we were an obstruction to their peaceful day.
Otherwise the rooms are modern, clean and comfortable, but why would you want to put up with such a ridiculously bad service on your vacation - please stay elsewhere, these people are as unfriendly as it gets.
Stay elsewhere, you've been warned.
