We booked this place with a baby and we arrived close to his bedtime, when we arrived the flat hadn't been cleaned at all, there was food on the floor, the kitchen sink was dirty, and the toilet was not clean at all. The hostel manager was very apologetic and cleaned the place himself within 10 minutes, although there were still marks in the bathroom.
The bed only has a thin sheet and in February was very cold, we were told that we would need to pay 10 euro per night for a heater.
Overall, we would stay again given the great location. We just had a few issues during the first night that made the stay more stressful than relaxing
