We are a family with two preschoolers. The apartment was spacious and clean, has a bathtub and good sized fridge. It was quiet and beds comfortable, even the couch bed. Bedding was clean and nice, apartment warm with good ventilation if required, plenty of amenities apart from toiletries so bring shampoo and soap.
For those with young children you may want to consider there are only very light curtains meaning it could be hard to get kids to sleep, it took our kids sometimes 90 mins to settle as it was so bright. Plus up early at 530 due to light. Would be better with blackouts.
The dishwasher and washing machine work well but the oven and stove are pretty old and need a lighter to light the gas, important if you plan to cook. There is also a lot of breakable glassware and crystal on display in the apartment which is fine unless you have little ones who want to touch it.
