I stayed at this property 1.5 years ago and it was nice, so I booked again. Unfortunately this time I was deeply disappointed. I arrived on a Sunday at 11:40 am and nobody was at the reception, with a notice on the door that reception is closed from 12 to 3. The cleaning lady seemed unable to help with opening the luggage storage. The reception guy explained that on weekends the front desk as well as the luggage room is closed from 12 to 3, but I was not notified about this at booking - if I knew that earlier I would store my luggage at the train station and go explore the city. Instead I was strained in the common room with my luggage for more than 3 hours (with another traveler in a similar situation). Of course I could go back to the station to store luggage and come back later but that would cost an additional 5.6 Euro for public transport in Bremen.
Let's also put away the fact that no one was there at 11:40 when the notice says 12, and that no one picked up the so-called 'please call if in emergency' phone in the 3 hours when we were waiting.
At checkout, another receptionist said that I did not pay for the reservation. I showed him the confirmation email with proof of payment from hotels.com but he still seemed unconvinced. Oh well...
And for the hostel itself it was alright except the fact that there's no elevator.
