Not a bad place for the price, but the bathroom was quite small, so we had some trouble as we are both quite tall! We found the apartment quite cold, but it soon warmed up when the electric heater was plugged in - this is the only source of heating though. Careful if you like to have long showers as well...we ran out of hot water on the first evening and my partner suffered for it!
The bed was very comfortable, which meant that we didn't want to get up in the mornings! It was quite a walk from the main city centre where we wanted to see the Christmas Markets, but there was lots of amenities nearby which was useful.
If you are looking for somewhere as just a base to stay, then this is ideal. If you are planning on spending time in the apartment, then it's not a very large space.
It was everything we needed though.
