Stayed in the apartment for two nights.
The location is fantastic being literally a 10 minute walk from the old city (and that's with baby in a push chair) and very safe. There are also bars, restaurants and both a supermarket and convenience store nearby.
We drove into the city and managed to park on the street nearby which was great as saved us some money and made carrying our stuff into the apartment very easy (which is good when with young child).
The communication was fantastic with quick responses. The hosts also kindly provided a cot for the baby which was setup when we arrived. Access was easy via a key left at the front desk of the building.
The actual apartment is a small studio flat which is all you need for a city break. It has a small kitchen with a fridge, hob and kettle etc - so all the basics. There is a nice modern bathroom with warm shower and a washing machine. The bed is big and comfy and there is also a sofa which can be folded out into bed as well.
All in all everything you will want in an apartment for a break. We loved it and the city.
Thank you guys!
