By far the worst place we ever stayed in:
1. Check in took 1 hour. Although they communicate reception to close at 23:00, it actually closes before 18:00. Phone no. for support is wrong - nobody answer the polish phone no., we had to call Germany
2. It was dirty. We found in the room spiders, bread crumbs on the chair, and the dirty cups
3. Water was cold, so we were taking cold showers.
4. No cleaning throughout our stay (4 nights). No new towels, toilet paper, etc. --> we ran out of toilet paper and started using tissues
5. Left water, coffee capsule for 1 person - booking was for 2 people
6. I complained at reception, phone, and in writing by email. The answer denoted extremely bad customer service - essentially they did not care that the room was dirty, they had cold water, etc.
