We stayed as a couple with a baby for a few days. We booked in the afternoon and asked for a baby crib for the same night and it was organised within 2 hours.
The flat is really beautifully furnished with a lot of useful extras like a washing machine, hair drier, shampoo and a kitchen with oven, microwave, stove... Sadly, there were two broken chairs and the cuttlery fell into pieces when we wanted to eat with it. For such a luxurious flat that was a bit disappointing.
The flat is in a cool neighborhood located with beautiful neighboring old town houses and the fine arts university close by. On the ground floor of the builing (and across the street) is a car repair shop, so it might get noisy.
Appart from the few above mentioned aspects we enjoyed our stay in the flat very much.
