This was perfect for our family of 5! The apartment is very quiet, facing a yard, which was important to us, so we could sleep well and get over our jetlag. At the same time, it is in a charming part of town, lots of nice shops, restaurants, bakeries, supermarket, short walk to various metro stations, very safe even at night, clean. Beds are comfortable, the pullout couch is way more comfortable than most pull out couches in the US :).
FYI for the kitchen: There is no oven. We didn't plan to bake anyway, but just don't buy frozen pizza. Also, there are only very limited dishes and small pots. This would be our one recommendation, so we could cook eg. some pasta to feed the whole family. But we loved it overall and would choose to stay there again!
