The location of this apartment is very good, as you have all the sights and museums in walkable distance, what was very convenient for exploring the city.
The train and bus station are less than 20 minutes away by foot.
As we stayed there for 6 nights, we could notice that the apartment is not the best option for two people as the water heater doesn't have a good capacity, being impossible to have two hot showers in a row. So you would have to plan your showers if you don't want to freeze, because it can take an hour or so to heat the water again. The house also have electric power limitations, not allowing the guests to turn more than 3 amenities at the same time, otherwise you would have to go downstairs to the building entrance for switching it back on.
However, the experience was positive as Isabella was willing to help us with all the questions that we had regarding the apartment. This summed up with the super good location, the good value for the money, make the stay here good.
