I stayed here with my five year old son for three nights. The location is perfect for exploring the city. It's very close to the old centre and the bridges and also well connected to public transport options.
The apartment itself has a nice old charm. Loved the huge windows and high ceiling.
From the reviews I already knew the toilet and shower are in the same tiny ' room'. This wasn't a problem for me, but I can see how for some this might be a bit inconvenient.
My only complaint was the bed. I like firm beds, but this one was not comfortable. It's a sofa that converts into a bed and though it looks good, it's not the nicest for a good sleep.
